Table 7. Impact of linkage to postnatal care by 6 wk postpartum, following 56% uptake at delivery.

Regimen	12-mo MTCT Risk (Percent) for Given Linkage to Postnatal Care
	0% Linkage	25% Linkage	50% Linkage	75% Linkage	87% Linkage (Base Case)	100% Linkage
sdNVP	19.8	19.2	18.7	18.2	18.0	17.7
Option A	17.1	16.3	15.5	15.4	14.4	14.0
Option B	16.2	15.4	14.6	14.0	13.4	13.0

To isolate the impact of linkage on postnatal care, results are shown for the base-case scenario of antenatal PMTCT uptake (56% uptake at the time of delivery).
