Subgroup analyses of primary outcomes by birthweight, gestational age, multiple pregnancy, mode of delivery and size for gestational age

* 26 infants in the intervention and 18 infants in the control group have their gestational age at birth missing. Size for gestational age could not be calculated for one additional infant that was born with indeterminate sex.

¥ adjusted by site and clustering due to multiple births. For the subgroup analysis by site, adjustment was only done for clustering due to multiple births.

**The widths of the confidence intervals were not adjusted for multiplicity, so the intervals should not be used to infer definitive intervention effects. The size of squares representing the point estimates is proportional to the weight assigned to the subgroup.
