Proportions of smear converted and non-converted per Lineages to estimate the effect of predictors in smear conversion using Fluorescein di-acetate vital staining technique; L = lineage 1, 2, 3, 4, 5 and 6; HIV = Human Immunodeficiency Virus; BMI = Body Mass Index; CI = Confidence Interval; p = Probability. L4 is not shown as it is the reference for the others. In addition HIV+ was fitted against HIV-, and AFB smear grade were fitted against smear negative.
