Data are no. of offspring with the outcome/no. of offspring assessed (% of offspring with the outcome). SE, standard error. 1 Maternal plasma 25(OH)D measured at enrollment; 2 Data are the mean outcome difference per 1 nmol/L increase of plasma 25(OH)D concentration. The mean differences and corresponding p values were estimated from linear regression models; * Significant difference at p ≤ 0.05 level.
