One-sided t-test and mean difference confidence interval were applied to test the primary hypothesis that the intervention group will improve the Bayley Scales of Infant Development 2ntl Edition (BSID-II) Mental Development Index (MDI) at 36 months compared to the control group among resuscitated infants. Two-sided t-tests and mean difference confidence intervals were applied to the BSID-II MDI scores among the non-resuscitated infants and the BSID-II Psychomotor Development Index (PDI) scores among the resuscitated and non-resuscitated infants.
