We performed a systematic review and meta-analysis to evaluate potential risk factors that might influence the severity of COVID-19. Studies were included in this review if they met the following inclusion criteria: (1) assessed the clinical manifestations and laboratory findings of patients with mild to severe COVID-19; The studies included in this systematic review also suggest that the levels of D-dimer were significantly higher in patients with severe COVID-19. Our data suggest that elevated levels of urea and creatinine, and not chronic kidney disease, were associated with severe COVID-19, which indicates that acute inflammation might be caused by SARS-CoV-2 infection. These data suggest that it cannot be determined clearly whether the elevated levels of liver enzymes in patients with severe COVID-19 are caused by direct infection or by drug-induced liver injury.	./cache/cord-328384-jzfr2t3p.txt	./txt/cord-328384-jzfr2t3p.txt
