Values are given as median (minimum-maximum) for continuous variables, and frequency for categorical variables. aMann-Whitney’s U-test for continuous variable, b Chi-square test for categorical variables. P-values of <0.05 were considered significant. X - mean, SD - standard deviation, d - days, g - grams, cm - centimeter, wk - weeks, yr - years, IVH - intraventricular hemorrhage, gr - grade, m - months, IUGR - intrauterine growth retardation
