a, b Relationship between our unadjusted surrogate of mechanical power (Eq. 3) and the reference formula (Eq. 1) in ICU patients treated with 5 cmH2O of PEEP: panel a shows the linear regression (R2 = 0.96), and panel b shows the Bland-Altman (bias = − 3.43 J/min; proportional error = − 0.27 J/min). c, d Relationship between our adjusted surrogate of mechanical power (Eq. 9) and the reference formula (Eq. 1) in ICU patients treated with 5 cmH2O of PEEP: panel c shows the linear regression (R2 = 0.98), and panel d shows the Bland-Altman (bias = − 0.53 J/min; proportional error = − 0.03 J/min)
