Weeks are completed weeks of gestation. INTERGROWTH-21st data have been converted from kg to grams and reported p-values represent a signed rank comparison of whether the observed median of the rural Kenya data differs from a hypothesized median value based on the medians reported in the INTERGROWTH-21st distributions (significant values in bold)
