Data are expressed as mean ± standard deviation. values express the difference in variables between the PTB and term delivery group based on a selected test. values in bold are statistically significant. PTB/term: mothers with preterm/term delivery; MW: Mann–Whitney test; KS: Kolmogorov–Smirnov test.
