Figure 3

Forest plot of estimating the mortality rate in COVID-19-ALI patients. The blue squares display the effect estimate (ORs), with the size of each blue square corresponding to the weight given to each study in the meta-analysis [22,27,28,30,31,32,33,34,35,36]. Horizontal lines or black arrow represent the 95% CIs corresponding to each effect estimate. The black diamond represents the overall effect of intervention, with its width representing the overall 95% CI. The I2 statistic represents a measure of heterogeneity. Overall effect OR: 3.64 [3.02, 4.39]; p <0.00001.
