Hello,
I'm looking at the Zimbabwe datasets in SAS and just as an example the variable HML32 = Final result of malaria from blood smear test. So far this seems easy enough for me to understand, but my problem is that in the dataset I see the variable HML32_01, HML32_02, all the way up to HML32_24 and this occurs with multiple variables and a lot of times there are 24 variations of the "same" variable.
Could someone explain to me what the difference or meaning of _01, _02, _03, etc. means. Is it the same test done at a different time, different person, same person different time? Also can I just combine all the variables HML32 to make one variable instead of 24 variables?

I would greatly appreciate any guidance on this matter. Is there something written about this somewhere that I am missing?

Thanks.
