Scatter plot of plasma 3-epi-25(OH)D3 and 25(OH)D3 in pregnant women during second trimester of pregnancy in a longitudinal cohort of pregnant women and their infants in Alberta, Canada (n = 537).
Pearson correlation coefficient showed a significant correlation between 25(OH)D3 and 3-epi-25(OH)D3 (r = 0.69, P<0.001).
