Abbreviations: CI, confidence interval; SGA, small for gestational age.

^*Odds ratios were generated through logistic regression, clustered by subject as subjects may have had more than one clinic visit before 2 years of age where data were collected. The adjusted model includes age at the time of clinic visit, gestational age, age at the time of discharge from the initial hospitalization and weight percentile <10% at the first clinic visit.
