Bland-Altman plot for sEMG-derived \({\mathrm{PTP}}_{\mathrm{mus,EMG}}/\hbox {min}\) via Eq. (3) against \({\mathrm{PTP}}_{\mathrm{mus}}/\hbox {min}\). The plot depicts PTP\(/\hbox {min}\) values for \(\textit{n}= {41}\) patients and in each patient one point per pressure support level is plotted, i.e., four points for each patient. The limits of agreement were calculated using a variant of the Bland-Altman method for repeated measurements, cf. [31]. The mean and \({95}\%\) interval are visualized via the solid grey line and dashed grey lines, respectively
