In patients who experienced acute liver injury during COVID-19 (n=140), the median ALT decreased from 118 (IQR: 124) during COVID-19 to 34 (IQR: 43) (p<0.0001); and median aspartate aminotransferase decreased from 142 (IQR: 141) to 30 (IQR: 33) during follow-up (p<0.0001). Here, GPT is linked to COVID-19.
