Hello EpiData friends,
Im having a little trouble that I would appreciate very much some help.
I have a rec file which I would like to create a subset. I tried to use the EpiData entry data export, using the filter option.
When I set the filter such as:
hepato <> 2 it is ok.
But when I set the filter as
alt1 >= 42
... or I set the filter as ...
(alt >= 42) or (hepato <> 2)
I get an error saying this is not a valid boolean expression. I tried in several different ways and I couldnt figure out what Im doing worng.
Any tip?
Abraço forte e que a força esteja com você,
