  • Mean (SE) differences of continuous variables (Δ) between the HIV uninfected and the reference groups (SE of 95% CI).

  • 1-150 Weight for length z scores at birth have been calculated for 66 HIV uninfected cases and 45 reference cases as standardised data were unavailable for lengths < 49 cm.
