Fig. 2From: Exploring causality in the association between circulating 25-hydroxyvitamin D and colorectal cancer risk: a large Mendelian randomisation studyAssociation of 25-hydroxyvitamin D (25-OHD) affecting genetic variants with log transformed 25-OHD concentration and colorectal cancer risk. The slope of the red line is the causal estimate derived from inverse variance-weighted (IVW) Mendelian randomisation and slope of the blue dash line represents the 95% confidence interval of IVW estimateBack to article page
