The Bland–Altman analysis of two variables reflecting the ΔPpl. The Bland–Altman analysis for the agreement between the cΔCVP-derived ΔPpl and Δd-Ppl (a) and between the ΔPes and Δd-Ppl (b). Solid lines indicate bias (a: − 0.3 cmH2O, b: 0.5 cmH2O). Broken lines indicate ± 1.96 standard deviation of the bias (a: 3.4 and − 4.1 cmH2O; and b: 3.9 and − 2.8 cmH2O). For comparison, data from the same pigs were marked with the same marker. cΔCVP-derived ΔPpl, ΔPpl calculated using a corrected ΔCVP; Δd-Ppl, change in directly measured pleural pressure; ΔPes, change in esophageal pressure; ΔPpl, change in pleural pressure
