The Poisson regression analysis showed that the adjusted IRRs of the non-MAFLD/low leg strength, MAFLD/high leg strength, and MAFDL/low leg strength groups compared with the non-MAFLD/high leg strength group after adjusting for age, sex, BMI, log maximum CK, number of diseased vessels, prior heart failure, hypertension, dyslipidemia, diabetes mellitus, smoking, log albumin, and log hemoglobin were 1.029 (95% CI: 0.463–2.287, p = 0.945), 2.390 (95% CI: 1.310–4.362, p = 0. The gene discussed is ALB; the disease is diabetes mellitus.
