<p>The incidence rate of LTFU was 17.6 cases/100 Person-Years of Observation (PYO). AIC results indicated that the parametric models outperformed the Cox model with the lognormal model being the best. Multivariable analysis indicated that HIV status and TB class were the only significant variables. HIV-positive patients were lost to follow-up at-least 3 times later than the HIV-negative patients. Those who had drug-sensitive TB were LTFU at-least 9-fold later than the drug-resistant patients holding other factors constant (TR=3.33, 95%CI=1.23-9.00) and (TR=9.21, 95%CI=1.44-58.71) respectively.</p>
