a

Data on four set of twins were not included in the analysis of gestational age and birth weight.

Missing data: nine BW values, four GA values and six peripartum haemorrhage values. Three twin births were of same sex, while one set of twins was of different sexes; thus, one set of twins and four missing sex values was not included in the analysis.
