Fig. 2From: PEEP application during mechanical ventilation contributes to fibrosis in the diaphragmFibrosis participates in ventilation-induced diaphragm dysfunction. A Bubble chart of the top 10 categories for GO enrichment of the MV group and the PEEP group (n = 3). B Volcano plot of differential gene expression of the MV group and the PEEP group (n = 3). C–K The diaphragm of the two groups was subjected to qPCR to analyze different type of collagen expression. Values are represented as the mean ± SD (*p < 0.05, **p < 0.01, ***p < 0.001)Back to article page
