After adjusting for sex, age, hypertension, and diabetes, we found that, as the hospitalization time increased, the ALT levels of asymptomatic group decreased, but the change was not significant (regression coefficient: −55.034, 95% CI: −110.564–0.496, P=0.053), the ALT levels of mild-common group slightly increased but not yet significant (regression coefficient: 6.821, 95% CI: −3.249–16.891, P=0.185), while the ALT levels of seriously-critically ill group showed a curve that was first flat and then decreased (degree of freedom: 1.809, P=0.002) ( Figure 2A ).
