Characteristics of mother-newborn pairs in the Dubowitz method (July 2001—May 2006) and HC/BPD biometry (April 2007—October 2010) cohorts.

Numbers are mean [SD], range or median {inter-quartile range}, range or number (%). GA: gestational age. CRL: crown-rump length. HC: head circumference. BPD: biparietal diameter. Malaria: at least one positive smear during pregnancy and/or prior to gestational age assessment. Severe anaemia at delivery: haematocrit <20%. #Malaria prior to estimation of gestational age from either the Dubowitz gestational age assessment or HC/BPD biometry measurement. *20 missing values for birthweight and newborn sex in HC/BPD biometry cohort. 19 missing values and 25 missing values for small for gestational age in Dubowitz cohort and HC/BPD biometry cohort, respectively, due to GA limits in Z-score equations or missing birthweight.
