Notes: Weight was measured at study enrolment and 21 days after enrolment; all other outcomes are for the period from enrolment to discharge. 1A conditional logistic regression method accounting for matched case-control data was used. The Mantel-Haeszel test was also applied for categorical data. The results from both methods were consistent. BPD, bronchopulmonary dysplasia; CI, confidence interval; FIC, family integrated care; IVH, intraventricular hemorrhage; NEC, necrotizing enterocolitis; PVL, periventricular leukomalacia; ROP3, retinopathy of prematurity, stage 3; SD, standard deviation; Wt1, weight on enrolment; Wt21, weight 21 days after enrolment; Zwt1, z-score for weight on enrolment; Zwt21, z-score for weight 21 days after enrolment.
