Many thanks Maarten for your advice. I managed to resolve it with the
following code:
forv i=0/5 {
foreach y in male singlet{
forv s=0/1{
di "myga==`i' & `y'==`s'"
qui su bwtg if myga==`i' & intab1==1 & admit_ic==1 & bwtg<. & `y'
if r(N)!=0{
tabstat bwtg if myga==`i' & intab1==1 & admit_ic==1 & bwtg<., stat(n
mean median p25 p75 min max ) by(`y') col(stat) f(%9.0g) notot nosep
}
}
}
}
