  1. One separate model was used for each predictor. All the models were used in multivariable analysis adjusting for the duration of mechanical ventilation (< 7-day vs. 7 days or more), chronic respiratory failure (Yes/No) and MRC (< 48 vs. 48 or more). An odds ratio (OR) > 1 signified an increased probability of necessity of mechanical ventilator assistance
  2. Italics indicate significant data
  3. VC vital capacity, FVC forced vital capacity, MIP maximal inspiratory pressure, MEP maximal expiratory pressure, PEF peak expiratory flow, PCEF peak cough expiratory flow
