Comparison of use of TNFα inhibitors and traditional DMARDs between cases and controls.
*TNFα inhibitors including Adalimumab, Certolizumab, Etanercept, Infliximab, and Golimumab
±Traditional DMARDS including Azathioprine, Hydroxychloroquine, Leflunomide, and Methotrexate
Note: Above each bar is listed the percent of patients taking that class of drug who have RA, whether in the case or control group; this should be contrasted to 8%, the percent of patients with RA in the full sample of cases and controls. For example, 93% of patients taking a TNFα inhibitor who did not get infections had RA, and 69% of those in the case group who were taking this class of drug had RA.
