Effect of a Lower Vs. Higher Positive End-Expiratory Pressure Strategy on Clinically Relevant Outcomes in ICU Patients Without Acute Respiratory Distress Syndrome: Bayesian Re-analysis of the REstricted Vs. Liberal Positive End-Expiratory Pressure in Patients Without Acute Respiratory Distress Syndrome (RELAx) Randomized Clinical Trial

Although the probability of benefit in the overall population was modest, the analysis suggested a higher probability of benefit in selected subgroups, particularly patients admitted for other reasons than cardiac arrest or intubated for other reasons than respiratory failure. These findings highlight potential heterogeneity of treatment effect and support further investigations.
