The number of genetic variants, effects, 95% confidence intervals, and P values of associations are contained. Two estimates under each subtitle represent the causal effect of SHBG levels on the corresponding type of arthritis in women and men, respectively. n_SNPs, the number of SNPs used as instrumental variables; Effect, the combined causal effect; CI, confidence interval; P value, P value of the causal estimateBack to article page
