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). Here, GPT is linked to chronic obstructive pulmonary disease.
