a
Multilevel model fixed effects: group (ASHA + =reference group), time (baseline=reference group), group X time, % ART adherence and covariates explaining group differences at baseline (age, quality of life, total MET, internalized stigma, social support, food insecurity, education).
b
SE=Program 1 (Standard Education); +NE=Program 2 (Nutrition Education); +NS=Program 3 (Nutrition Supplements); +NENS=Program 4 (Nutrition Education & Nutrition Supplements).
c
SE (Program 1)=reference group.
d
Baseline (Month 0) is the reference group.
e
Baseline and SE (Program 1) are the reference groups.
f
Addative effect are presented, rather than the interaction term.
