Supplementary Material for: Relationship between Apgar Scores and Morbidity and Mortality Outcomes in Preterm Infants: A Single-Centre Cohort Study

Introduction: Apgar scoring in modern practice has extended beyond the original described remit by Virginia Apgar, including prognostication. Prognostic value of Apgar scoring in preterm populations is unsupported by robust evidence. Objectives: We aimed to identify the association between mortality or a composite mortality/major morbidity outcome in preterm infants with 1-min, 5-min, and sum 1 + 5-min Apgar scores. Methods: Seven-year retrospective data was analysed on neonates born Results: 394 infants were included in the analysis. In neonates born Conclusions: Apgar scoring at 1 and 5 min has limited prognostic accuracy for extremely preterm infants but is prognostic in older infants. Sum Apgar scores, a measure of initial condition and response to resuscitation, may be a better predictor of mortality than individual scores.
