Ann Rheum Dis. 2019 Mar;78(3):320-327. DOI: 10.1136/annrheumdis-2018-214326Differences in baseline characteristics and numerical differences in IR of SI between ABA, RRTX and TOZ were observed. The relative risk (RR) of SIs seemed to vary modestly with drug.TNFi treated RA patients in large observational studies have suggested an initial twofold increased risk of SIs compared with biologic-naïve patients. Long-term observational studies on the risk of SIs in patients treated with non-TNFi bDMARDs are sparse.This study aimed to estimate crude as well as age and gender-a...
