Additional file 1: Table S1. PEEP difference between groups according to different grouping criteria. Table S2. Outcomes comparison between PEEP < 6 and PEEP ≥ 6 after propensity-score matching. Table S3. Outcomes comparison between PEEP < 8 and PEEP ≥ 8 after propensity-score matching. Figure S1. Correlation between set PEEP and delta P/F ratio (P/F at T24h minus P/F on admission)
