Re: EpiData-list Digest, Vol 53, Issue 3

by epidata-list＠lists.umanitoba.ca

Dear Pedro, Thank you for your kind reply. I plan to review medical records using paper form. Expecting to have 1 observation at baseline to be entered in baseline file and 6-24 observations for time of follow-up, will be entered in follow-up file. Then data will be entered twice and compared (around 600 patients in total). I am trying to find an alternative way to collect data using papers. Palm would be solution but more expensive etc.. Thank you in advance and best regards ziad On Thu, Mar 6, 2008 at 10:02 AM, <epidata-list-request(a)lists.umanitoba.ca> wrote: > 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.

I've struggled for hours to get it to work the way it did under Epi Info. Basically, there are three conditions in an IF statement. I've tried with the two simple conditions alone and the script works (condition at the beginning & at the end). Combining conditions always gives the 'atrisk' calculated variable the answer "N".

Re: EpiData-list Digest, Vol 53, Issue 2 - Review Medical records

Dear Ziad, Your question is rather non specific, but I ve been through a similar experience with some bad memories. Review medical records is not an easy task.

CHK file with calculations does not work as it did in EpiInfo

by epidata-list＠lists.umanitoba.ca

Hi, I wonder if someone can spot the syntax problem in this CHK file for the Beck Depression inventory. I've struggled for hours to get it to work the way it did under Epi Info. Basically, there are three conditions in an IF statement. I've tried with the two simple conditions alone and the script works (condition at the beginning & at the end). Combining conditions always gives the 'atrisk' calculated variable the answer "N". Is there a limitation or syntax difference in Epidata?? Here's the syntax. thanks for the help.

Random selection of records

by epidata-list＠lists.umanitoba.ca

Dear Jamie, Thank you so much for the solution for the query INCOMPATIBLE KEY VARIABLES. It worked well. Can you please help in two other situation also ? 1. There is a file say try.rec Is it possible to read it and write another file with 5 randomly selected records or selecting every 4th record (as done in systematic sampling). The documentation of the commands such as SET RANDOM SEED and RANDOM SIMULATIONS is not clear in the help file. I am attaching a sample file try.zip. 2.What is the equivalent of SET LISTREC=ON/OFF (EPI6) in Epi Analysis ver 2.03 ? With regards, Dr. Shavinder Singh

Complex if statements (was chk file with calculations ....)

by epidata-list＠lists.umanitoba.ca

For the suggested chk file command: > IF N9SUICIDE = 3 or (N9SUICIDE = 2 AND TOTAL >= 16) or TOTAL > 42 > THEN > ATRISK="Y" > ELSE > ATRISK="N" > ENDIF > I would always write: IF ((N9SUICIDE = 3) or ((N9SUICIDE = 2) AND (TOTAL >= 16)) or (TOTAL > 42)) then most likely this would/should also work: IF (N9SUICIDE = 3) or ((N9SUICIDE = 2) AND (TOTAL >= 16)) or (TOTAL > 42) then In other words: Always be very explicit with parenthesis. Test and report please. regards Jens Lauritsen EpiData Association

Using EpiData to review medical records

by epidata-list＠lists.umanitoba.ca

Dear EpiDataLister, It is semi-technical question. I intend to review medical records retrospectively for patients on ARVs. It seems to be involving lot of papers to review their history to be able to enter them into EpiData. Meant to check if someone had similar experience to share how did you sort it out? Thank you in advance and best regards ziad

Screen Flickering in Epidata data entry

by epidata-list＠lists.umanitoba.ca

I'm using epidata on thinkpad winXP sp2 laptop- all drivers are updated: One "bug" which is very annoying is that the whole screen output constantly flickers and is unstable when I enter data. It seems like the whole screen sort of disappears with every key that is pressed. This bug is only present in the data entry form Is this something which can be prevented?? thanks -- Jannik
