Data, since 1997 in Istanbul Union against Tbc, were taken from the central archives. Of P-Tbc cases, 27% (174/640) was female, 73%(466/640) was male. Of A-Tbc cases, 46% (193/419) was female and 54% (226/419) was male (p= 0.0001). While 3.4% of P-Tbc cases (22/640) was between 0-14 years old, it was 7.8% (33/419) in the A-Tbc group (p= 0.002).
