Univariate Cox proportional hazards screening of risk of TB among patients attending public HIV treatment facilities in Brazil (n = 463) between January 1, 1995 and December 31, 2001.

*Denominators vary due to missing data from the patient medical record for characteristic (missing values deleted from analysis)^Reference value appears bolded on the second line of each characteristic. Note that those patients who received ART non-HAART and were later switched to HAART were classified as patients having received HAART (see data analysis section of Methods)^^The word ”Total” in the “No. with feature/Total” column refers to the denominator for each particular characteristic (e.g., 81 out of a total of 157 patients who did not receive HAART were treated with ART non-HAART exclusively)#The total number of patients who developed TB (n = 39) varies for each characteristic according to whether or not patients were excluded from analysis due to incomplete information (in the patients' medical record) for that characteristic
