Fig. 1 Comparison of corrected QT (QTc) interval by rheumatoid arthritis-related parameters. No association is observed between the QTc interval and sex, diabetes, or the presence of rheumatoid factor (RF) or anti-citrullinated protein antibodies (ACPA) (1A, 1B, 1D, and 1E); Patients with hypertension or an erythrocyte sedimentation rate (ESR) higher than 30 mm/h have longer QTc intervals (1C and 1F).
Fig. 2 Comparison of corrected QT (QTc) interval by disease activity indices. The analysis of variance indicated that patients with elevated disease activity show significantly longer QTc intervals (p < 0.0001).
