> > > >sort ID PERIOD POFFSET >gen MARK=1 >if (ID = ID[-1]) and (PERIOD=PERIOD[-1]) then MARK = 0 This is a great approach. I just want to add something. According to my understanding, this would make MARK=1 for the records with the smallest number of one set of ID and PERIOD. But it does not necessarily mean that the record with MARK=1 would be closest the expected date. In this example, > Each period I select (M3, M6, M12...)

This is because patients did not always respect their > appointment dates. for some reasons, if the patient came at 81 and 93 days, PERIOD would be -9 and 3 respectively and the record with PERIOD=-9 would be selected (MARK=1) which is not desirable. To avoid this situation, we just need to neutralize the minus sign of POFFSET by doing this before sorting ID PERIOD POFFSET. So, I would suggest the following command: if POFFSET<0 then POFFSET= -1*POFFSET[_n] sort ID PERIOD POFFSET gen MARK=1 if (ID = ID[-1]) and (PERIOD=PERIOD[-1]) then MARK = 0 Best wishes, Zaw > Message: 5 > Date: Mon, 27 Aug 2012 08:23:24 -0400 > From: epidata-list(a)lists.umanitoba.ca > Subject: Re: [EpiData-list] Epidata analysis > To: epidata-list(a)lists.umanitoba.ca > Message-ID: <BLU0-SMTP250E7B96809BAD9A83BDABFDA20(a)phx.gbl> > Content-Type: text/plain; charset="windows-1252" > > The approach to this would be: > > - create the new variable that identifies period (I'm not sure why you use > more than one) (PERIOD) > - create a new variable that equals the number of days between expected > and actual visit (POFFSET) > - SORT the data on patient ID, PERIOD and POFFSET > - create a new variable to mark the first record you find for a given > patient and period (MARK) > You do the last two steps like this: > > sort ID PERIOD POFFSET > gen MARK=1 > if (ID = ID[-1]) and (PERIOD=PERIOD[-1]) then MARK = 0 > > MARK will set to zero for the second visit for any patient in a period > (because ID and PERIOD will be the same as previous) > > Jamie > > On 2012-08-27, at 3:11 AM, epidata-list(a)lists.umanitoba.ca wrote: > > > I have a “.rec” Epidata data set with patients with chronic diseases > > (Diabetes and Hypertension).

Epidata analysis
by epidata-list＠lists.umanitoba.ca 27 Aug '12

27 Aug '12

I have a “.rec” Epidata data set with patients with chronic diseases (Diabetes and Hypertension). I would like to undertake some analysis to determine what is happening on the patients at different periods of follow up. (Month 3, 6, 12........) i.e. Glucose levels, BP, BMI....... Each period I select (M3, M6, M12...) I give an allowance of + &- 10 days. (e.g. for M3=90 days from the day of enrollment, I select between day 80 and day 100). This is because patients did not always respect their appointment dates. In the period selected (between day 80 -100) some patients for several reasons were seen more than once. I would like to select only one visit date in case of moth 3 follow up that is closest to the 90th day from date of enrollment .(e.g. a patient had a visit on the 80th day and 95th day, I want to select the 95th day visit which is closest to day 90)..... How do I do this with Epidata analysis? NB: My variables are “enrolment date” and “visit date” Kwal

100% converting rec to epx
by epidata-list＠lists.umanitoba.ca 27 Aug '12

27 Aug '12

Now it is clear that the converting (aka Import, "Add data structure...") of REC-files into the new epx-format doesn't work 100%tly. Plausibility checks are not importet. This is one of the BUGs I can see. Maybe there get more lost in the conversion. Is there a bug-tracking system where I can add and monitore it? Where can I see the development time table? I really need to update my project to the new format. Of course I need a complete converting routine for it. I won't do any work again that was done before in the old version.

Epidata version 3.1 - build 22feb2005
by epidata-list＠lists.umanitoba.ca 26 Aug '12

26 Aug '12

I really need an older version of EpiData to do some tests. How can I get "Epidata version 3.1 - build 22feb2005" ? I've never used it. But I converted old rec-files to epx-format. Now there is now plausibility check or default values while entering data with EntryClient. I am not sure if it causes in the conversion or if it is "normal" because the old rec-files behave the same way. I need to test it.

In the download section I can see "EpiData EntryClient" and "EpiData Entry". What is the difference?

multi-sheet project
by epidata-list＠lists.umanitoba.ca 20 Aug '12

20 Aug '12

I have 7 old REC-files. I imported them to the new data format with "add structure". I saw that I can append all sheets together to one big sheet. But I don't want it. Is there a way to create one project (epx-file) with 7 separate sub-sheets in it?
