Comparison of PAI-1, PAI-2, PAI-1/PAI-2 ratio, and vWF in relation to vitamin D status. PAI-1, PAI-2, PAI-1/PAI-2 ratio, and vWF in the group of vitamin D deficient pregnant women (serum 25(OH)D levels ≤50 nmol/L) compared to the group of pregnant women with high adequate vitamin D status (serum 25(OH)D levels ≥100 nmol/L). Error bars depict mean and 95% confidence interval. P-values were calculated using Mann–Whitney tests for PAI-1 and vWF, while t-tests were used for PAI-2 and PAI-1/PAI-2 ratio after logarithmic transformation. Notably, the difference in PAI-2 levels were still significant when excluding the single measurement above 70 ng/mL (P = .018). Abbreviations: 25(OH)D, 25-hydroxy vitamin D; PAI-1, plasminogen activator inhibitor 1; PAI-2, plasminogen activator inhibitor 2; vWF, von Willebrand factor.
