Thanks for your response. I realize the questions are rather basic, but I had perused many of the help and intro files, without finding anything that specifically addressing syntax. Perhaps the intro file for beginner users could be made more user friendly with an additional paragraph in bold under the section: Value label: For categorical data this defines the meaning of the values. E.g. 1=man 2=women. The values are edited via the + . The drop-down list lets you pick an existing label definition. ACCEPTABLE SYNTAX with all the rules spelled out, such as when quotes are necessary etc. Susan Quoting epidata-list-request(a)lists.umanitoba.ca: > Send EpiData-list mailing list submissions to > epidata-list(a)lists.umanitoba.ca > > To subscribe or unsubscribe via the World Wide Web, visit > http://lists.umanitoba.ca/mailman/listinfo/epidata-list > or, via email, send a message with subject or body 'help' to > epidata-list-request(a)lists.umanitoba.ca > > You can reach the person managing the list at > epidata-list-owner(a)lists.umanitoba.ca > > When replying, please edit your Subject line so it is more specific > than "Re: Contents of EpiData-list digest..." > > > EpiData-list mailing list > ___________________________________ > > Today's Topics: > > 1. value labels error message (epidata-list(a)lists.umanitoba.ca) > 2. legal use?

RE: How to use browse in the middle of analysis
by epidata-list＠lists.umanitoba.ca 10 Jun '08

10 Jun '08

The easy way to use browse is: Hit the F6 button. This will move control to the browse window and show all current data Obviously a pgm cannot be running in the background, but a strategy whereby: The system to help beginners is the "dialog" / menu system, which you find using the toolbar. By using the dialog there is no need to know the options for most standard possibilities. 1. For beginners: a Use the menu's and the toolbar to create a command, e.g. in analysis find the tables part b In the menu's (dialogs) there is a "more" arrow. When clicking this more options show up. By the menu's most standard options are available, but for some see the "experienced". 2. Experienced a Write the command in the command prompt. b If in doubt of options, click the F1 button and the help file for that command will be shown in the viewer. 3. Run the command / execute the command 4. When all is in place and running. Open the pgm file editor (F5) and insert history Clean up in the lines and you have your working pgm ready.

Thank Chrystine, To solve this issue, one way (of course may not be the best) is to append datasets (providing ID are different) using EpiData Entry/Analysis which ever is convenient for you). Not sure if merge is an appropriate way for such combination of datasets. If the two datasets have some common features such as unique key values for example ID, then merge may be required to deal with it. Alternatively try append, the two file or more files should be combined to produce one. Perhaps the memory needs to be cleared prior to READ other files, then append/merge them to be READ in one file. First of all "cls" to clear the screen out then "read". Save replace, save your new dataset (golden rule).

Hi Jamie Sorry I sent the message without finishing my section on multiple data sets. Working with Multiple data sets in Epidata Analysis What I was going to say was our first attempt at working with several copies of an outbreak dataset had been sucessful. This was a timing thing - we wanted to get the data in more quickly. We had already entered 150 records when we decided to use another data entry person, but that was Ok the process still worked. Our steps were 1. Created a file and entered records (outbreak1) 2. Used Tools copy structure to create a new file (outbreak 2) 3. Entered records in both outbreak 1 and outbreak 2 4. Used Data in/out then Append/merge option B to create a new file outbreak_final, that was outbreak1 and outbreak 2 combined. What was good about this was that it was easy, and I also really liked the option to copy the check file we had set up for the first file to use with the new file when you copied the structure. The only thing I didn't like so much was we ended up with a duplicate ID which we wouldn't get with an autoID (which we usually use for our ID field) but I used a number field rather than AutoID this time as I thought it would be a problem with the merge to have auto ID. Using Multiple data sets in Epidata Analysis - READ and multiple data sets Could you explain a bit more about how to do this. When I try and READ more than one data set it says "no data will be lost close first". Then - what does the SAVEDATA do - create a new file like MERGE does? Which do you recommend to combine data - Merging in Epidata entry or in Analysis. Using Epidata analysis in a field epidemilogy course I'm very interested in how you use Epidata Analysis in your field epidemiology course . Would I be able to find out a bit more about this from you - perhaps off the list to avoid taking up too much time on this topic? As I am involved in teaching courses using epidata/epi info to support field epi I am very interested in what you cover in your courses but realise others may not have the same interest Many thanks Christine For multiple data sets (we do this every year in our Field Epidemiology Course), you can use Merge in EpiData Entry or just READ multiple data sets on one line in Analysis and then SAVEDATA.

RE: [EpiData-list] Outbreak analysis diary - Defining cases as a newvariable
by epidata-list＠lists.umanitoba.ca 08 Jun '08

08 Jun '08

Hi Alistair Thank you for that. I found a copy of your training manual for using Epidata/Epi Info for analysing outbreaks on the web and think it is excellent. Yes it is an interesting question about whether to change to Epidata Analysis for outbreak analysis. Like you I teach courses in using Epidata/Epiinfo and am interested in it from an ease of teaching/ease of use perspective as well as for my own use. For my own use I am pretty sure I will change to Epidata analysis. We just had another small outbreak come up at the same time as the one I have been writing to the list about and my colleague wanted the data analysed in a hurry. Data had been entered in a questionnaire that was based on our standard epidata master one, just as the large outbreak was. I copied the programme I had written and saved for the large outbreak in Epidata analysis - made a couple of small changes - and was able to print out a symptoms profile, Epicurv graphs and two full attack rate tables - one with the outcome sick and one for the outcome of case (the case definition was created as part of the programme) for the 25 foods of interest less than 15 minutes. I thought that was pretty good. For my training courses though I am not so sure. A large group coming to these are field staff who are new and/or infrequent users of any outbreak analysis software. At the moment my instinct is that although Epidata Analysis does things more quickly and has some great features- especially the attack rate tables which are brilliant - I think Epi info is easier for these new or infrequent users to understand. I am thinking I may see if their is interest in me developing a one day course to introduce Epidata Analysis to people in public health units who are likely to take on a regular role analysing outbreaks, and stick with my current Epi info course for the wider group who want a very basic knowledge - so that it an emergency they could get out the manual and follow the instructions if the main person is away. I am interested to see though that the Health Protection Agency in the UK is offering both beginning and advanced one day courses for in Epidata Entry/Epidata Analysis. I saw the course outlines on the web http://www.hpa.nhs.uk - click on training and events - but I would love to see if I could have a look at their training notes. Do you know anything about these courses? In terms of a basic set of introduction notes I found the training notes (pdf file) provided by the International Union against Tuberculosis and Lung disease very helpful. The link is http://www.tbrieder.org then go to Epidata best wishes Christine >>> <epidata-list(a)lists.umanitoba.ca> 6/06/2008 7:41 p.m. >>> Christine These notes are really useful, thank you! Like you I have 'traditionally' used EpiData for questionnaire design and entry, and then switched to Epi Info for Windows for the more user-friendly (to me at least) data analysis. Hopefully your experiences will give a good idea to others about the readiness of EpiData Analysis for use in this type of situation. Thanks Alastair --------------------------------------- Alastair Tomlinson Chartered EHP, Lecturer in Environmental Health 029 2020 1528 AGTomlinson(a)uwic.ac.uk -----Original Message----- From: epidata-list(a)lists.umanitoba.ca [mailto:epidata-list@lists.umanitoba.ca] Sent: 05 June 2008 06:05 To: epidata-list(a)lists.umanitoba.ca Subject: [EpiData-list] Outbreak analysis diary - Defining cases as a newvariable Today we started doing the analysis of exposures for our outbreak. First we need to create a new variable, as not everyone who is sick meets the case definition for the outbreak. Case definition Our case definition is someone who has diarrhoea and/or vomiting 24-72 hours after the function. I used the programme editor to define a new variable called Case I made case a Boolean field so the relative risks would calculate correctly (with a Boolean field the Y appears first in a two by two table and then the N and this is what you want to calculate relative risks correctly). Diarrhoea and Vomit - the fields I needed to create the Case field were also Booklean fields. For a long time I had a problem as I was trying many combinations of If Diarrhoea = Yes or Y or "Y" in my code and it was not working. Then my workmate suggested I try TRUE. I think this is confusing as when you print a Frequency of a boolean Field it prints as Y. Anyway here was the code that worked. Define case <Y> If Diarrhoea = TRUE or Vomit = TRUE then case = TRUE This deals with the first part of the case definition - that they must have diarrhoea or vomiting. The next part is that they are NOT a case if the symptoms started on the same day. The code I ended up using for this was IF onsetdate <= date("24/05/2008") then case = FALSE. I had to put the date function as well as the date itself or the code would not run. I don't know why that is but any other combination I tried like "24/05/2008" or 24/05/2008 or ("24/05/2008") did not work. Onsetdate In the last post I asked if anyone had some code to create a single onset date from two pieces of information - the vomitdate and the diarrhoea date. My workmate helped me figure out something that worked and this is it. If diadate < vomdate then onsetdate = diadate If vomdate < diadate then onsetdate = vomdate If vomdate =diadate then onsetdate = diadate If vomdate =(.) then onsetdate = diadate If diadate =(.) then onsetdate = vomdate Now we have a variables of case and onset date and I created an Epicurv graph using them. It was great. One more frustration. While we were working on the code we often used browse to check our results. We wrote the browse command into the programme editor but the results of the Browse do not appear in the output so I had to do it over again each time in the output screen. I tried list instead of Browse but this didn't work either. Any suggestions for how you can build the output from a browse or line list command into a programme will be welcome.

Re: Outbreak analysis diary - attack rate table
by epidata-list＠lists.umanitoba.ca 08 Jun '08

thanks very much Jens, Hans and Jamie for the suggestions and Alistair for the encouragement. Hans thanks I tried your suggestion for the browse and it worked well. The other suggestions will take a bit longer to work through. I will report back when I do but this post I want to report on the analysis and also the success of creating and combining two data entry files. Attack rate table of exposures As has been said several times on this list but is worth saying again, the 'outbreak analysis' function in Epidata that creates a single attack rate table showing attack rates, relative risks, CIS and pvalues of all exposures of interest against the outcome of 'case' is a wonderful feature. The command is TAB CASE .....all exposures of interest/OA The steps I took were: 1. Click on Browse Data from the menu bar 2. Tick my outcome of interest (Case) and all my exposures of interest (foods etc) 3. Click on Paste (this copies all the selected variables into the section at the bottom of the output screen) 4. I then copied this line into the programme editor, took out the browse at the start and added/OA at the end as below: TAB CASE ANYFOOD COURTL1 COURTL2 JUNGLEPLAY JTOILET BTOILET KIOSK M1NUGGETS M2CHEERIOS M3CHIPS M4SAUCE M5PIZZA M6JUICE M7JELLYICE M8YOGURT M9CHOCCRAC M10CAKE M11LOLLIES M12TEA M13COFFEE M14SAV M15SAND M16HOTDOG M18FISHBIT M19FISHFIL M20FRUITSA M21DANISH M22BURGER/OA Note: Adding EX after OA gives the pvalue I then selected run programme - this creates the attack rate table in the output screen, and also in the default output file. I really like the outbreak analysis feature but on my wish list would be 1. for 'outbreak analysis' to be an option in one of the menus somewhere. I only knew about this feature through someone mentioning it on the list and I had to search through the docuentation to find it. Maybe this was what the 'attack rate plus RR' option was but I could not seem to select this - it stayed greyed out. 2. If a select' has been used for this to show above the attack rate table. I ran the outbreak analysis above again but this time selecting only people who had attended the centre on a certain date. The command I used was Select Day25 = TRUE I know the select has worked because N has gone down from 251 to 66, but there is no indicaiton on the output file or the information under the attack rate table that a 'select' is in place. Thank you all again for your feedback on these postings. I will do one maybe two more - covering the process of sending the data output to a report and a final summary of the main steps and final programme I used. Christine Having more than one data entry file We ended up with 250 questionnaires so decided we would try using several data entry operators to enter the data Christine Roseveare Analyst Regional Public Health 570 9194 027 495 9671 >>> <epidata-list(a)lists.umanitoba.ca> 6/06/2008 8:56 a.m. >>> Dear Christine: Just a quick comment on BROWSE. Did you use the command: set display databrowser=on before issuing the BROWSE field1 field2 command? The default is that the browser is off. Note that this works fine with the public release version, but if you experiment withe (marvelous) test version build 134, there seems to be some hickup that occasionally blocks the program, but I believe to have noted that it works if the command is in the beginning of the program before reading the file (not yet certain). In any case, I appreciate your telling us your experiences, they are useful for many. Apologies for not taking the time to answer to more of your queries, but I am currently a bit taken with traveling between continents.
