ART, antiretroviral therapy; BF, breastfeeding duration; RRRF, relative risk of replacement feeding; HFS, HIV‐free survival.
Bolded numbers indicate HFS at 12 months (2010 WHO Recommendation). Red box indicates base case scenario (RRRF = 3, 24‐month ART duration, median infant/child mortality). Yellow indicates maximum HFS for each ARV duration.
