Enrollment and birth outcomes by CD4 cell count stratum and time of delivery. If the date of delivery was not known (lost to follow-up or maternal death), then women were grouped according to their expected date of delivery determined on the basis of the date of the last menstrual period and assuming a delivery at 38 weeks of gestation (the mean gestational age at delivery in this cohort). Shaded areas denote women with outcomes after 14 November 2003 who qualified for cotrimoxazole treatment during pregnancy. ARV, antiretroviral.
