Fig. 5From: Impact of a positive end-expiratory pressure strategy on oxygenation, respiratory compliance, and hemodynamics during laparoscopic surgery in non-obese patients: a systematic review and meta-analysis of randomized controlled trialsForest plot for DP (as a surrogate of Cdyn) comparing MPEEP vs. iPEEP groups. 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 DP 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;DP: driving pressure; Cdyn: dynamic compliance; MPEEP: moderate positive end-expiratory pressure; iPEEP: individualized positive end-expiratory pressure groupBack to article page
