ART, antiretroviral treatment; ARV, antiretroviral; CI, confidence interval; NGO: non-governmental organisation.

Working/active: able to perform usual work in or out of the house; ambulatory: able to perform activities of daily living but not able to work; bedridden: not able to perform activities of daily living.

^*The model was simplified using Akaike’s Information Criterion, retaining predictors and clinically plausible interaction terms that increased model fit, with a penalisation for increasing model complexity.
