The Bland–Altman analysis of each variable is classified by intravascular volume. The a, b, and c figures show the Bland–Altman analysis for the agreement between the cΔCVP-derived ΔPpl and Δd-Ppl in the intravascular volume condition set to low (a), normal (b), and high (c), respectively. The d, e, and f figures show the Bland–Altman analysis for the agreement between the ΔPes and Δd-Ppl in the intravascular volume condition set to low (d), normal (e), and high (f), respectively. Solid lines indicate bias (a: − 0.3 cmH2O, b: − 0.5 cmH2O, c: − 0.2 cmH2O, d: 0.6 cmH2O, e: 0.5 cmH2O, and f: 0.5 cmH2O). Broken lines indicate ± 1.96 standard deviation of the bias (a: 2.5 and − 3.2 cmH2O; b: 3.9 and − 4.9 cmH2O; c: 4.0 and − 4.3 cmH2O; d: 4.0 and − 2.9 cmH2O; e: 3.9 and − 2.8 cmH2O; and f: 4.1 and − 3.0 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
