Model variables predicting completion outcome
| Variable | Chi-squared# | AOR (95% CI) |
| Age¶ | 15.5 | 1.04 (1.02–1.06) |
| Clinic attendance before treatment | 10.4 | 0.54 (0.37–0.78) |
| Choice of regimen | 23.3 | 0.43 (0.30–0.60) |
| Constant | 0.3 | NA |
Adjusted odds ratio (AOR) and 95% confidence intervals (CI) were calculated using binary logistic regression and all variables entered by forward stepwise method. Nagelkerke R2 for the model is 0.12. NA: not applicable. #: Wald statistic, which identifies variables that significantly contribute to the model (all entered variable p-values for Wald statistic were <0.01; constant p = 0.56); ¶: continuous variable.
