Pairwise comparisons (Holm-Sidak test) revealed significant differences between the TNL and TL groups ( P = 0.017) and the TNL and PTL groups ( P = 0.025) and borderline significant difference between the TL and PTL groups ( P = 0.050), demonstrating more distinct differences in methylation at this site between non-labor and labor tissues than between term and preterm tissues.
