  • This table presents historical data concerning maternal characteristics and birth data of the offspring, who participated in the second follow-up in 2012–2013. Data are mean (SD), median (25th–75th percentiles), or percentage (number) unless otherwise indicated.

  • NA, not available.

  • *Analysis of differences between the two groups were performed by independent samples t test, Mann-Whitney U test, or χ2 test, respectively. P values <0.05 are bold.
