CD4 and tuberculosis: In a multivariate model adjusted for age, sex, marital status, distance between living place and the clinic, confirmed tuberculosis and CD4 cell count, independent risk factors of loss to follow-up were a CD4 cell count below 100 cells/μl at starting cART (OR 2.55, 95% CI 1.45-4.50, p = 0.001) and living more than 100 km away from the clinic (OR 3.02, 95% CI 1.40-6.56, p = 0.005).
