Fig. 4. Scatter plots of genetic associations with years of education against the genetic associations with RA. The slopes of each line represent the causal association for each method. The blue line represents the IVW estimate, the green line represents the weighted median estimate, and the dark blue line represents the MR‐Egger estimate. SNP: single nucleotide polymorphism, RA: rheumatoid arthritis, MR: Mendelian randomization, IVW: Inverse-variance weighted.
