test version of analysis ready (read epx file - new Odds Ratio calculation)
by epidata-list＠lists.umanitoba.ca 07 Nov '10

07 Nov '10

A new test release of EpiData Analysis has been placed for download on the testing page. http://epidata.dk/testing.php The zip file contains a complete working copy, including updated help file. When you unzip please maintain folder structure. An EPX formatted version of bromar data is included in the zip file. Changes from previous releases are: A. Ability to read xml formatted files created by EpiData Manager (EPX) files (NOT EPZ zipped files) B. The default principle of Odds Ratio calculation has been changed from: MLE based to: Standard simple with Robins, Greenland, Breslow 95% CI to get the new default Odds Ratios use: /o , to use the same as previously: /oex Output is slightly changed, example: . tab runok sex /o /oex Outcome:Marathon race completed ? Sex of runner 1 0 Total 2 3119 418 3537 1 437 53 490 Total 3556 471 4027 Exposure: Sex of runner = 2Outcome: Marathon race completed ? = 1 Odds Ratio = 0.90 (95% CI: 0.67-1.23) (Robins,Greenland,Breslow CI) Exact (MLE) Odds Ratio = 0.90 (95% CI: 0.66-1.23) pORex<=1.0 = 0.2872 With this test release users are more than welcome to challenge the whole cycle of creating files in Manager (including import fra Stata, Rec, QES files, pasting via clipboard or editor etc), entering data with the EntryClient and analysing the data in Analysis. You may use the Manager to export data to Stata for comparisons of results. Anything not working - or comments to the way we have implemented aspects - please report to this list or if you find reproducible errors it is easier for us, if you can report to the flyspray system - see link on the testing page. regards Jens Lauritsen

An error message while executing the command in Epidata analysis
by epidata-list＠lists.umanitoba.ca 29 Oct '10

29 Oct '10

Dear all, I got an error message while executing commands of Epidata analysis on a new machine with Windows 7. Please see the message within the quotation marks. " Cannot open file "C:\Users\Gateway\AppData\Local\Temp\TMPCC04.Tmp". The process cannot access the file because it is being used by another process " This happened when I hit F8 or F9 and the command was not executed. But it did work when I hit F8 for several times. Could anybody tell me why it happened and how to solve this problem? Thank you for your support. Zaw Myanmar

Datetime conversion resource
by epidata-list＠lists.umanitoba.ca 27 Oct '10

27 Oct '10

Hi list members From time to time on the list we have discussed the value of having a datetime variable in Epidata. This is something I would find like, as the 'epidemic curve' is something that is an important part of any outbreak investigation. For short outbreaks that carry on over more than one day both the time and date are useful so youcan show numbers becoming ill every 6 hours for example over two or three days. The ability to map by datetime is one reason I often use EpiInfo for outbreak analysis, although I enter data in Epidata. I wanted to let any interested members know that a colleague has developed a simple text file that can be run as a programme in EpiINfo that coverts data entered in EPidata to a single datetime for use in EPiInfo. If you have entered an onset date as a date and onset time as a number with a decimal (e.g. 15.30) the programme converts the information into a single datetime variable - it can then be mapped using the EpiInfo histogram graph. Jens if you think this is useful at all would you like me to post this somewhere? Also is there any thought of creating a time field in Epidata? thanks Christine Christine Roseveare Analyst Regional Public Health 570 9194 027 495 9671 >>> <epidata-list(a)lists.umanitoba.ca> 22/10/2010 10:47 p.m. >>> For all users Today new versions of Entry Client and Manager have been placed on thehttp://epidata.dk/testing.php page for general download and testing.

Input for decision of sequence in development of new functionality, please comment
by epidata-list＠lists.umanitoba.ca 26 Oct '10

26 Oct '10

Priority of developments The current sequence of developments until the first production release contains these elements. 1. Release of test version of EpiData Analysis, which can read EXP files (possibly EXZ) - expected this week. 2. "show structure" form to Manager 3. Control structures level 1 (value labels, range) --- test release 4. Multi language in forms and labels 5. Control structures level 2 (mustenter, jumps, "type comment") 6. Control structures level 3 (define unique key and search in data) --- test release 7. Solve known deficiences (from Flyspray and list) - e.g. idnum fields 8. Printing of dataforms in EntryClient --- test release 9. Enhancements for production of fast datasets, e.g. copy from question banks 10. Further developments, e.g. GCP (Good Clinical Practice Principles). Please discuss on this list at what level of function You find first release should be made - provided obviously at that level the function as such is stable. My current decision is after point 8. It would also be good to get statements during the coming months of which decisions you make locally on the conversion to the new principles - e.g. you are ready to use it at that moment, or you find the current EpiData Entry better for your purpose, or you decided to start using other software and the reasons for that.

Hi Jens and the Epidata team thank you for all the work you are doing on the new development. In terms of the timeline I am wondering about when the new build might be stable enough to be used for training courses? At the moment I teach one or two courses a year to public health staff on using Epidata and EpiInfo to investigate disease outbreaks. They use the current version of Epidata and I am wondering about when I should try and change to the new version. thank you Christine Christine Roseveare Analyst Regional Public Health 570 9194 027 495 9671 >>> <epidata-list(a)lists.umanitoba.ca> 22/10/2010 10:47 p.m. >>> For all users Today new versions of Entry Client and Manager have been placed on thehttp://epidata.dk/testing.php page for general download and testing.

NIH requirements for Data management
by epidata-list＠lists.umanitoba.ca 20 Oct '10

20 Oct '10

Dear EpiData friends, Recently I was talking to a friend about the professionalism of research x professor-student structure in research and then he showed me a past call of NIH grant wich in part I pasted here. I was somehow surprised, because I didnt know that all these should be in a project. Data and Biostatistics Core: Required. Each application must include a The Data and Biostatistics Core is a resource to the multi-project application, providing for the data management and statistical support of the overall Center and individual research projects. The Data and Biostatistics Core has several components: an electronic data management system, a data management implementation plan, and biostatistics support. A full-time Data Manager must be present onsite at the Center or at the place where the electronic data management system is hosted and statistical expert(s) should be available as needed. Applications must provide a detailed description of the existing or planned data management system. The data management system must be capable of collecting and managing data from the participating study sites in order to ensure uniformity of procedures and high quality data. The data management system should reside at the endemic area site(s) and data management staff will be responsible for the design, development and testing of databases and data management software, validation of the data system, training of data management and field personnel on data collection procedures and activities, maintenance of the database and software systems, documentation of changes, and preparation of data dictionaries and standard operating procedures for all aspects of data management. Each TMRC and related field sites should have computers, connectivity to the internet and communications capabilities. For sites without such capabilities, funding for such infrastructure should be budgeted in this core and the infrastructure should be in place before the end of the first year of the grant. The data management system should include, but is not limited to: • security features for controlled access to all project data; • a tracking system for data forms, activities, and study samples; • date and time stamping of all data records; • audit trails to track all changes made to data records; and • a reporting system that generates error reports and summary information reports. If applicants do not have the capability for the data management system at the time of application submission, the applicant should describe a plan for designing and implementing a fully operational data management system based on the system requirements, including provisions for the time frame for design, development, testing, validation, and training activities. Plans and procedures must be in place to provide security against anticipated risks, including loss of confidentiality of subject electronic records and data summaries. Each TMRC should have staff with data management (Data Manager) expertise at each site. The Center should have access to dedicated statistical expertise that informs the research study design and provides the ability to conduct statistical data analysis. They should provide for activities such as study design and protocol development and where appropriate, generating interim tables, preliminary statistical analyses for progress reports, and assisting with statistical issues related to laboratory testing and results.

Dear all, When I try to export my data into SAS, all my variables appear into a single column (in SAS). What could be happening? When I export the data into Excel and then to SAS it does work perfect. Is there any difference from exporting a data file directly from EpiData into SAS other than EpiData into Excel and then SAS?

Order of how yes no settings appear in tables
by epidata-list＠lists.umanitoba.ca 13 Oct '10

13 Oct '10

Hi Jamie A little while ago when you answered my question about changing the Boolean fields to 0-1, you mentioned there was a way in both EpiData Analysis and EpiInfo to reverse the order that two by two tables were shown, that would help in a situation where 0 was no and yes was 1 (so the 1 or yes answers appeared first in the table). I have looked around Epi Info but couldn't find a setting like this. Could you let me know how to do it? And also how to do it in Epidata analysis? I Many thanks Christine Christine Roseveare Analyst Regional Public Health 570 9194 027 495 9671 >>> Christine Roseveare 20/09/2010 5:21 p.m. >>> Hi Jamie Could you please explain why you changed the booleans to 0-1 before loading it into manager? Sorry if this is a silly question. I am asking because someone recently gave me an outbreak file where they had used 0 and 1 (created in Excel 0 = no and 1 = yes). The problem was that when I came to analyse it (in this case using Epi Info) it meant that the two by two tables were in the wrong order. Because no was 0 it came out first in the table. I have always used the boolean field in epidata for our outbreak questionnaires and it has worked very well. They come out in the right order in both Epidata Analysis and Epin Info, and also make intuitive sense to the data entry person. thank you Christine Christine Roseveare Analyst Regional Public Health 570 9194 027 495 9671 >>> <epidata-list(a)lists.umanitoba.ca> 13/09/2010 2:34 p.m. >>> I successfully loaded a moderately-sized .rec file (changing all booleans to 0-1 before loading into Manager--it should prompt to do that for us).

adding variables to existing rec
by epidata-list＠lists.umanitoba.ca 12 Oct '10

12 Oct '10

To add a variable to an existing REC file, I tried what was discussed on: http://lists.umanitoba.ca/mailman/htdig/epidata-list/2010q2/001427.html But I didn't have it very clear. I finally made it doing the following steps (using EpiData 3.1, under Microsoft Windows): 1) Editing the QES adding a variable with a temporally name as "new". 2) Then, Tools -> Revise Data File 3) Tools -> Rename Fields 4) I go to the new variable and then edited the subsecuent variables with a temporally name also. The added variable should finally have the name 'P1103e' and the subsecuent variables must be "moved". In that sense the new variable would be called 'newe' and the subsecuents of the same block of questions can be called 'newf', 'newg', 'newh', 'newi', 'newj', and so on. 5) Then, I just go again to Tools -> Rename Fields 6) I then rename the variables with the appropiate names as: 'P1103e', 'P1103f', 'P1103g', 'P1103h', 'P1103i', 'P1103j'. 7) Finally, I changed the QES file with the appropiate names and then Tools -> Revise Data File. This steps worked fine for me.

how to share epidata files?
by epidata-list＠lists.umanitoba.ca 08 Oct '10

08 Oct '10

Dear epidata-list members, I'm a new member and I'm quite new also in the use of Epidata. I need some support. My team is coordinating a multicentre study. At the beginning of the study we prepared a database (files .qes, .chk and .rec) and sent it to all centres; during the study they send back to us regularly the updated .rec files with the records. We have problems in receiving via e-mail, as attached documents, epidata files (especially files .rec with records, but also without records). We sometimes are not able to open the files, or sometimes we manage to open the files but the records are not there. We realised it depends also on the e-mail server used by every centre, and on other variables too. I wonder which would be the best way to share epidata databases. Many thanks Alessandro

Dear EpiData list. With the latest release of the EpiData Manager and EntryClient some changes were made to the format of datafile. Therefore the test files from today contains an updated sample file. Please delete older versions. During the development phase of Manager and EntryClient changes to the XML structure should be expected, e.g. the latest extension specifying timed recovery backup. As soon as the first public release is available for routine usage we will make sure that coming versions can read all older files. But during the developments this will not be the case. In the meantime we will provide a working sample file for each new test version such that it is possible to see the capabilities of the program. The exe files uploaded today are the same as yesterday, except that the sample file is contained. Kind regards, Torsten Bonde Christiansen.

New Manager and EntryClient test version released.

Dear EpiData list. As of this morning (danish time) new test versions of both EpiData Manager and EpiData EntryClient have been released on our testing website: http://epidata.dk/testing.php Please be aware that the back-end code for the testing website have been changed, so if you experience any problems with downloading the files please report directly to me on: tc "at" epidata.dk The major changes for these version are: * A "timed recovery backup" system has been implemented in the EntryClient. At a given interval (this is set in EpiData Manager within "Project->Settings->General") a recovery backup is save to disk with the same filename as the project file but with an additional extension ".bak". On a clean close of the program this file is deleted, hence a regular user should not notice the existence of this file, but if the program crashes unexpectedly the file will remain an upon trying to load the original file, the user is informed that a recovery file exist and advised to load the recovery file. * In addition to the "timed recovery backup" system, it is no also possible to specify that a complete backup of the project file is taken on close/shutdown (again, this is specified in EpiData Manager). The backup is NOT used as part of the timed recovery system, hence the used is not noted of the existence upon loading the original file. This is merely meant as a "daily backup" feature, that gives the user the possibility of storing backups of the daily work. In the future this option is probably going to be a lot more configurable by the manager, but for now the original file is "just" stored with the same filename, but containing the date of saving. * Both Manager and EntryClient now has a feature that allow for checking on-line if a new version of the program exists. This naturally requires an active Internet connection, but if no such exists a non-fatal warning is given. * In addition to the above a small number of bug-fixes and speed improvements have also been implemented. Kind regards, Torsten Bonde Christiansen. EpiData Association.
