I don't know what adherence level is, and thus I don't know
whether -pillcount < 95- defines adherence level.

However,

(week >= 2 | week <= 24)

does not mean "during weeks 2-24".

| means "or". You want & for "and".

My dataset has different time points, weeks 2,4,8,12,16,20,24,36 and
52 weeks on treatment.
I want to look at the adherence level during the weeks 2-24, I tried
this code, but it didn't give me what I wanted:

gen adherence =0
replace adherence =1 if pillcount <95 & (week>=2|week<=24)
