In three different multivariate logistic regressions, adjusting for low ALT, age, sex, socioeconomic status, sector, diabetes, hypertension, ischemic heart disease, chronic renal failure, dementia, COPD, asthma, BMI, COVID vaccination status, and low ALT were associated with death (OR 1.88, 95% CI 1.37–2.56, p < 0.001) and long hospitalization (OR 1.78, 95% CI 1.33–2.35, p < 0.001). The gene discussed is GPT; the disease is diabetes mellitus.
