We only included severe versus non-severe COVID-19 pneumonia patients and pooled results were summarized by STATA 12.0 software.Two researchers independently selected the study and assessed the quality of the included studies. The heterogeneity was measured by I tests (I < 50 indicates little heterogeneity, I≥50 indicates high heterogeneity). Publication bias was ruled out by funnel plot and statistically assessed by Begg test (P > .05 as no publication bias).
