DAS28: disease activity score including 28-joint count; CRP: C-reactive protein; bDMARD: biological disease-modifying antirheumatic drug; tsDMARDs: targeted synthetic disease-modifying antirheumatic drug; MTX: methotrexate; TMP-SMX: trimethoprim-sulfamethoxazole. Values are median (interquartile (IQR)). The values were determined using the nonparametric Wilcoxon signed-rank test and Fisher’s exact test. .
