1Separate analyses were done for each level of each stratifying factor; e.g., among patients aged <30, 28 (9%) patients from selective DOT and 8 (7%) from universal DOT were resistant, with an OR of 1.3 associating increased resistance with selective DOT. Analyses were adjusted for age, race, and/or HIV status, as appropriate, depending on the stratification factor.
