Relevant patient demographics and clinical characteristics are detailed, according to their ALT levels (lower or ≥ 17 IU/L), in Table 1: patients in the low-ALT group were, as expected, older (67.9 ± 13.5 vs. 63.7 ± 12.9 years, p < 0.001), had lower body mass index (BMI) values (26.6 ± 4.9 vs. 28 ± 5.1, p < 0.001) and had higher percentages of diabetes mellitus (26% vs. 22%, p = 0.036), arterial hypertension (57% vs. 51%, p = 0.017) and atrial fibrillation (9.5% vs. 6.1%, p = 0.008). Here, GPT is linked to atrial fibrillation.
