Fig. 2From: Variables predicting weaning outcome in prolonged mechanically ventilated tracheotomized patients: a retrospective studyFailure rates of prolonged weaning and SBT in patients classified by quartiles of LTC-MP. Failure rates are presented as percentage (%), LTC-MP as mean values, and standard deviation. SBT, spontaneous breathing trial; LTC-MP, mechanical power normalized to dynamic lung-thorax compliance; Q1-4, patients classified by quartiles 1-4 of LTC-MPBack to article page
