^a Half of the clusters in each study arm were randomized to standard counseling and half to standard plus nutrition counseling.

^b This is not the expected number of participants as many ART patients do not live in the cluster (i.e., in the area surrounding the healthcare facility), and are therefore not eligible for this trial
