  1. Adjusted for sex, gestational age, highest parental education (at time of BSID assessment), insurance. Parameter estimates (95% CI) represent change in BSID-III composite scores per increment in growth (1.0 z-score or 1.0 kg/m2 in BMI). Statistically significant values with p < 0.05 are in bold.
  2. #Denotes p < 0.01.
