Genotype and allele frequencies of the SEPS1 G-105A polymorphism in preterm neonates delivered with or without PROM and controls.

NOTE: Due to genotyping failure, the actual sample size, respectively, was 566 and 673 for cases and controls.Abbreviations: OR, odds ratio; CI, confidence interval.aORs and P values obtained against reference by χ2 test (2×2).bTwo-sided χ2 test for distribution of allelic frequencies (df = 1).cORs and P values were calculated by multivariate logistic regression, adjusted for maternal age at delivery (year) and neonatal sex.
