say this in different words: Statistical Analysis The study employed appropriate statistical methods to analyze the data. Differences in mean 25(OH)D concentrations between groups were assessed using ANOVA, and the relative risk for achieving a 25(OH)D concentration of 80 nmol/L or greater was calculated using relative risk ratios with 95% confidence intervals. The significance level was set at p < 0.05. Results The results indicate that the mean 25(OH)D concentrations at delivery and one month before delivery were significantly different between groups, with the highest sufficiency achieved in the 4000 IU group. The relative risk for achieving a concentration of 80 nmol/L or greater was significantly higher in the 2000 and 4000 IU groups compared to the 400 IU group. The study also found that circulating 25(OH)D had a direct influence on circulating 1,25(OH)2D3 concentrations throughout pregnancy, with maximal production in the 4000 IU group. Importantly, there were no differences in safety measures between groups, and no adverse events were attributed to vitamin D supplementation
