Meta-Analysis
Methods
Systematic review and meta-analysis of randomized controlled trials; searched Web of Science, Scopus, PubMed/Medline, and Embase from inception to July 2024; random effects model (DerSimonian and Laird method)

Background and aim

Even though the role of D2 (ergocalciferol) on cardiovascular disease risk components has been studied, conflicting results have been reported. Moreover, no single study has studied all these parameters and the role of vitamin D2 individually has not been assessed; hence, this systematic review and meta-analysis of randomized controlled trials was conducted to assess the effect of vitamin D2 supplementation on lipid profile, anthropometric indices, blood pressure, and inflammatory and glycemic biomarkers in humans.

Methods

Web of Science, Scopus, PubMed/Medline, and Embase were searched from database inception to July 2024, and the random effects model, according to the DerSimonian and Laird method, was used to generate combined estimates of the intervention's effect on the outcomes.

Results

After full-text analysis, 11 eligible articles were included in our meta-analyses. No statistically significant association was observed between vitamin D2 administration and BMI, WC, TC, HDL-C, LDL-C, TG, DBP or SBP; however, a statistically significant decrease in CRP (WMD: - 1.92 mg/dL, 95 % CI: - 3.30 to - 0.54, P = 0.006) and HbA1c levels (WMD: - 0.37 %, 95 % CI: - 0.66 to - 0.09, P = 0.009), and a non-statistically significant decrease in FBG (WMD: - 4.61 mg/dL, 95 % CI: - 14.71 to 5.47, P = 0.370, I2 = 90 %, P ˂ 0.001) and HOMA-IR (WMD: - 0.10, 95 % CI: - 0.17-0.03, P = 0.002) were detected.

Conclusion

In summary, our systematic review and meta-analysis discovered that vitamin D2 administration was associated with a statistically significant decrease in CRP and HbA1c levels, without a significant correlation with other outcomes.
