^*The total number shown for each group is the number of mother–infant pairs included in the analysis. Only women whose infant had an evaluable outcome were included.

^†Comparison between intensification and observational groups. The Fisher exact test was used to compare proportions, and the Wilcoxon rank-sum test to compare distributions of continuous data.

^‡Women could enroll in the study after cART initiation. VL before cART was available for 67 women in the intervention group and 143 in the observational group.

^§One woman had twins.
