Model results.

aWe assumed that the proportion of women tested for syphilis in the antenatal care setting in the 20 African countries that do not report such data is equal to the weighted average (40.7%) of the 23 African countries that do report it. Should the current rate of syphilis screening turn out to be lower than 40.7% in these cases, the number of events and DALYs averted, as well as direct medical cost, would increase proportionately.
