Clinical characteristics by weight growth velocity (WGV) score.

Continuous variables are expressed as mean (SD). Categorical variables are expressed as incidence (%).* indicates that data for some infants were missing.The number of missing values for the WGV scores 6 to 14 and total, respectively, are as follows:Maternal age: n = 12, 1, 11, 20, 34, 49, 34, 12, 17, 190; Diabetes: n = 0, 0, 0, 1, 0, 0, 0, 0, 0, 1; Chorioamnionitis: n = 1, 0, 1, 6, 4, 3, 0, 1, 1, 17; PROM: n = 0, 0, 0, 1, 1, 0, 0, 0, 0, 2; Antenatal corticosteroid: n = 0, 0, 0, 1, 0, 1, 0, 0, 1, 3; Male sex: n = 0, 0, 0, 0, 2, 1, 1, 0, 0, 4; AS 1 min WGV; weight growth velocity, SD; standard deviation, PROM; preterm rupture of membrane, SGA; small for gestational age, AS; Apgar score, RDS; respiratory distress syndrome, CLD; chronic lung disease, PDA; patent ductus arteriosus, NEC; necrotizing enterocolitis, IVH; intraventricular hemorrhage.Clinical characteristics by weight growth velocity (WGV) score.
