Cohort accrual diagram and study design. The figure shows the three parent studies [2729] in which HIV negative donors were enrolled, counselled on HIV risk reduction and followed-up prospectively and how the nested case–control subset was accrued. For the case control analysis of HIV acquisition, 154 women who acquired HIV were compared with 155 women who remained HIV negative through follow-up. For cohort analyses of HIV course, 154 women who acquired HIV and were followed up for up to 120 months were studied. Follow-up time and disposition as at 1 August 2014 (date of censorship), is shown in the lower panel for each donor where dot color denotes disposition (green: remains in follow-up, red: exited study as commenced cART or death, black:lost to follow-up)
