GPT and COVID-19: In multivariate analysis, high AST/ALT ratio (adjusted OR 99.9; 95% CI [2.1–4280.5]; P = 0.02), BUN (adjusted OR 1.64; 95% CI [1.01–2.66]; P = 0.047) and lactate levels (adjusted OR 30.53; 95% CI [2.1–444.4]; P = 0.012) on admission were relatively independent risk factors for poor prognosis of the COVID-19 patients (Table 4).
