Fig. 11From: The efficacy of extracellular vesicles for acute lung injury in preclinical animal models: a meta-analysisSecondary outcomes of the meta-analyses of the ALI with EVs group compared with the ALI without EVs control group. Secondary outcomes are BALF neutrophil count(A), total number of alveolar cells(B), alveolar leukocytes count(C). The size of each square represents the proportion of information given by each trial. Crossing with the vertical line suggests no diference between the two groups. ALI acute lung injury, IV inverse variance, CI confdence interval, df degree of freedomBack to article page
