  1. ANC Antenatal care. aMean. Difference of CD4 cell count between visits was performed as follows: firstly, the absolute value of the difference of CD4 cell count between the first antenatal visit and six-months visit, and between the first antenatal and 12-months visit was calculated among all the pregnant women (total and stratified by AHD and without AHD). Afterwards, the same calculations were repeated only for women with negative differences (decrease in CD4) between visits
