Fig. 2From: Physiological predictors of respiratory and cough assistance needs after extubationReceiver operating characteristic (ROC) curves for data recorded before extubation: peak cough expiratory flow (PCEF), peak expiratory flow (PEF), forced vital capacity (FVC), slow VC, and maximal inspiratory (MIP) and expiratory (MEP) mouth pressures.
