proc sql;
create table want as
select * from have
where prxmatch("/1|Y|yes/i",Results_In_Death)
union
select * from have
where prxmatch("/fatal/i",OutCome)
union
select * from have
where prxmatch("/death|dead|fatal|(subject|patient|participant).*(expire)/i",Term_Verbatim)
union
select * from have
where prxmatch("/na/i",Death_Date)=0;
quit;
the idea is to subset the dataset have that meet the where condition.but the results are not expected. for example results_in_death is showing values like 0,na etc.
also outcome is showing values like disease progression etc
how to subset the data just based on where conditions?
Don't you mean
proc sql;
create table want as
select * from have
where prxmatch("/1|Y|yes/i",Results_In_Death)
and prxmatch("/fatal/i",OutCome)
and prxmatch("/death|dead|fatal|(subject|patient|participant).*(expire)/i",Term_Verbatim)
and prxmatch("/na/i",Death_Date)=0;
quit;
Note that the parentheses in the third test seem oddly placed.
it is OR not AND
If you use OR then you will get dates not equal to NA or results_in_death not equal to yes. Why are you surprised?
