*---------- begin example ------------
/* generate some data */
drop _all
set obs 100
forvalues i = 1/12 {
gen week`i' = ceil(6*uniform())
}
/*at least once poor adherence*/
gen poor = 0
forvalues i = 1/12 {
replace poor = 1 if week`i' > 5
}
/*count number of poor adherence patients*/
count if poor == 1
*--------------- end example -------------
