The MR estimates from each method of assessing the causal effect of years of education on the risk of RA

MR method	Number of SNPs	Beta	SE	Association p-value	Cochran Q statistic	Heterogeneity p-value
Inverse variance weighted	49	−0.754	0.283	0.008	81.03	0.002
MR Egger	49	−2.320	1.709	0.181	79.56	0.002
Weighted median	49	−0.950	0.355	0.008	80.75*	0.002*

MR: Mendelian randomization, RA: rheumatoid arthritis, SNP: single nucleotide polymorphism, Beta: beta coefficient, SE: standard error. *Maximum likelihood method
