Relationships between in utero HIV exposure and infant anthropometry at birth and 12 weeks (a–e) and Apgar scores (f). Infants who were HEU (n = 32) had lower head circumference Z-scores at birth (d; p < 0.001) compared to infants who were HUU (n = 22). There were no other differences between infants who were HEU compared to HUU for anthropometry at birth or 12 weeks of age. Outlier box plots are measured anthropometry and Apgar scores (quartiles, median lines and 95% confidence diamonds, *p < 0.05 [ANCOVA]). HUU HIV-unexposed, uninfected; HEU HIV-exposed, uninfected; CI confidence interval
