1 Pulmonary TB status was based on culture, except if culture data were missing in which case microscopy results were used. From each of 355 consecutive PTB positive TB patients, an age- and sex-matched neighborhood control was selected, and used as reference category.
2 Adjusted for sex and age. Age was included as dummy variable with below 25 years as reference category. N = 1604, R2 = 0.23, intercept 736 (95% CI: 695; 778).
