  1. aMedian regression analysis accounting for intrafamilial correlation between twins. Values are reported as β (95% CI) and P-value.
  2. bModel 0 is unadjusted; Model 1 adjusted for gestational age at birth, birthweight z-score, sex, and PMA; Model 2 adjusted for same variables as Model 1 plus mean protein intake.
  3. cβ estimates indicate median differences in body composition z-scores compared with reference group in the lowest tertile of human milk lactoferrin concentration (Tertile 1).
