First trimester serum 25-hydroxyvitamin D concentrations in women who remained normotensive (n=131) and women who developed subsequent preeclampsia (n=39). First trimester 25(OH)D levels were not significantly different in who developed subsequent preeclampsia compared to normotensive women (mean ± standard error=27.4 ± 1.9 vs. 28.8 ± 0.80, p=0.435). To express total 25(OH)D levels (ng/ml) in nmol/L, multiply by conversion factor 2.496.
