GPT and COVID-19: Given the limited data, we aim to perform a meta-analysis and systematically review the current data available on liver injury in COVID-19 with two main objectives: (i) to draw more generalized conclusions about the abnormal serum markers of liver injury such as albumin, alanine aminotransferase (ALT), aspartate aminotransferase (AST), and bilirubin in laboratory-confirmed COVID-19 patients; and (ii) to determine its relationship with the severity of COVID-19.
