The median AST (63 (55) vs 19 (13), P < 0.001), ALT (68 (62) vs 21 (13), P < 0.001) of COVID-19 patients with liver injury were significantly higher than those of the control group, with the median higher than the upper limit of the reference range, but not more than twice the upper limit (Table 1). This evidence concerns the gene GPT and injury.
