Fig. 6From: Correlation of maximal inspiratory pressure to transdiaphragmatic twitch pressure in intensive care unit patientsThe top panel presents the cumulative mortality of patients (y axis) as a function of PdiTw (x axis). The bottom panel presents the cumulative mortality of patients (y axis) as a function of the Pimax (x axis). Regression lines represent best curve fits of data to inverse third order exponential equations, with equation parameters and statistical information presented in Table 1. Both PdiTw and Pimax were significant predictors of cumulative mortality.
