I'm not sure if this is an SPSS question..but I've lost patience.



I am trying to determine the % of subjects who experience an adverse event
(symptom) by their treatment group (1,2, or 3).



Each subject could have reported multiple adverse events, so the data looks
like this:



Subj ID              AE                    Txt group

1                      2                      1

1                      2                      1

1                      3                      1

1                      4                      1

2                      2                      2


2                      3                      2

2                      3                      2

2                      4                      1



A simple frequency produces 103 AEs for a total number of 104 subjects in
the group (since each can report multiple AEs).



I don't even really need to know %, just those AEs reported by more than 10%
of subjects.



I know there are lots and lots of smart people out there.phone home..
