FIGURE 3.
Subgroup analysis for all included studies of acute lung injury that reported the primary outcome of lung injury score. Each row represents pooled estimate data from studies within that subgroup. Data is presented as a forest plot with standardized mean difference and 95% confidence intervals. I2 value represents the statistical heterogeneity within each subgroup. Effect sizes < 0 favours EV treatment and > 0 favours control. The ‘Overall Efficacy’ is a pooled estimate effect of MSC‐EVs on lung injury score from all studies combined
