Forest plot of associations with HLA in the discovery cohort. Estimated odds ratio (OR) with 95% confidence intervals (CI), P‐value and C‐statistic for the independently associated HLA types HLA‐C*14:02, HLA‐B*08:01, HLA‐C*02:02, HLA‐B*07:02, and HLA‐A*31:01 in 1) all discovery cases and controls, 2) Swedish discovery cases and controls, and 3) Swedish discovery cases with matched controls. Matched controls were individuals who had been treated with sulfasalazine and/or had been diagnosed with inflammatory joint or bowel disease. The effect is adjusted for sex and genetic principal components 1–4. HLA = human leukocyte antigen.
