The columns in this table are: (2a) year; (2b) source for estimating the number of infants exposed to prenatal and intrapartum ARVs; (2c) number of infants exposed to prenatal ARVs out of (2d) the total number of infants in the study; (2e) raw proportion and (2f) smoothed proportion of infants exposed to prenatal ARVs; (2g) point estimate and (2h) 95% CI for the number of infants exposed to prenatal ARVs; (2i) number of infants exposed to intrapartum ARVs out of (2j) the total number of infants in the study; (2k) raw proportion and (2l) smoothed proportion of infants exposed to intrapartum ARVs; (2m) point estimate and (2n) 95% CI for the number of infants exposed to intrapartum ARVs. Symbols: number (n), total number (N), raw proportion (p) and smoothed proportion $(\tilde{p})$ .
