Abstract
Introduction:
The evidence for the incidence and severity of liver injury in Chinese patients with coronavirus disease 2019 (COVID-19) is still controversial. The purpose of this study was to summarize the incidence of liver injury and the differences between liver injury markers among different patients with COVID-19 in China.
Methods:
Computer searches of PubMed, Embase, China National Knowledge Infrastructure (CNKI) and medRxiv were used to obtain reports on the incidence and markers of liver injury in Chinese patients with COVID-19, from January 1, 2020 to April 10, 2020. (No. CRD42020181350)
Results:
A total of 57 reports from China were included, including 9889 confirmed cases of COVID-19 infection. The results of the meta-analysis showed that among the patients with early COVID-19 infection in China, the incidence of liver injury events was 24.7% (95% CI, 23.4%–26.4%). Liver injury in severe patients was more common than that in non-severe patients, with a risk ratio of 2.07 (95% CI, 1.77–2.43). Quantitative analysis showed that the severe the coronavirus infection, the higher the level of alanine aminotransferase (ALT), aspertate aminotransferase (AST), total bilirubin (TB), alkaline phosphatase (ALP), γ-glutamyl transpeptidase (GGT), and the lower the level of albumin (ALB).
Conclusion:
There is a certain risk of liver injury in Chinese patients with COVID-19, and the risk and degree of liver injury are related to the severity of COVID-19.

Results from LimitationRecognizer: We detected the following sentences addressing limitations in the study:Owing to data limitations, we did not further analyse whether liver injury increases the risk of death in patients with COVID-19. Our study also has some limitations. First, although there is no obvious bias in the definition of liver injury and detection of liver injury markers, some of the results are still heterogeneous. Second, this study only analysed the data of Chinese COVID-19 patients, not remote data analysis. Third, it is not possible to further describe the effects of other confounding factors, such as complications, age, and gender, on the results of the study; these confounding factors are also difficult to adjust. Fourth, most of the included studies are retrospective analyses, some are cross-sectional studies, 22 are manuscripts that have not been peer-reviewed, and there is a danger of bias in data collection.
