IVW Inverse variance weighted. IVW was based on multiplicative random effects. nsnp the number of single-nucleotide polymorphism. Beta: the regression coefficient based on 25OHD raising effect allele. SE: standard error. p < 0.05 represents the causal association of serum 25OHD levels with MS. OR Odds ratio. OR_lci95 Lower limit of 95% confidence interval for OR. OR_uci95 Upper limit of 95% confidence interval for OR
