a Model-1. Controlled for all variables in the table.
b Model-2. Model 1, except for BMI and glycemia; 95% CI with p values ≤ 0.099 shown in bold; In sensitivity analysis, additional models were evaluated: Model 1A. When glycemia was replaced by diabetes (2 categories) in Model 1, diabetes remained associated with TB in adults (adj-OR 4.08, 95% CI 2.13, 7.80), but not in the elderly [adj-OR 1.70 (0.65, 4.45)]. Model 1B. Addition of education or health insurance did not modify the associations already observed in Model 1.
