Among 4218 (25.9%) of women with documented CD4 count in pregnancy, the risk of severe adverse outcomes was higher in women with CD4 > 500 than CD4 < 500 cells/mm3 when baseline weight was >70 kg, but lower if baseline weight was 60 kg or less, whereas macrosomia and maternal hypertension were similar across baseline weight groups when stratified by CD4 (Table 5) and there was no significant interaction by CD4 count for any of the outcomes. Here, CD4 is linked to Large for gestational age.
