Forest plot for Cdyn comparing different PEEP strategy groups: (a) LPEEP vs. MPEEP; (b) LPEEP vs. HPEEP; (c) MPEEP vs. HPEEP. Data are presented as mean differences and 95% confidence intervals. The vertical line represents no effect with the value of 0. The diamond represents the pooled mean effect estimate with 95% CI. It provides an overall measure of the difference in Cdyn values between different PEEP strategy groups. Abbreviations: CI: confidence interval; SD: standard deviation; I2: the ratio of excess dispersion to total dispersion; Тau2: the variance of the true effect sizes; Chi2: observed weighted sum of squares; df: degrees of freedom; Cdyn: dynamic compliance; LPEEP: low positive end-expiratory pressure group; MPEEP – moderate positive end-expiratory pressure group; HPEEP: high positive end-expiratory pressure group
