Continuous variables are expressed as median and 25°/75° percentiles, and compared by the Mann–Whitney U test; categorical variables as number of patients (%) and compared by the χ2 test. SSc, Selvester score; fQRS, fragmented QRS; VT, ventricular tachycardia; VF, ventricular fibrillation; HF, heart failure; and MACE, major adverse cardiovascular event.
