Associations between corticosteroidtherapy used in COVID-19patients and prevention of mortality in COVID-19 patients were analyzed using meta-analysis. A meta-analysis was performed for the obtained odd ratio values and 95% confidence interval (CI) from the articles. A pooled estimate was calculated for the effect of corticosteroid therapy on mortality and graphically summarized in a forest plot using Microsoft Exceland Graphpad Prism software. Random effects and fixed effects models were used for meta-analysis. Cochran’s Q test and the I2 statistic were performed to assess the statistical heterogeneity.
