Fig. 3From: Exploring red cell distribution width as a biomarker for treatment efficacy in home mechanical ventilationReceiver operating characteristic curves against 50% reference lines for different potential treatment efficacy markers of home mechanical ventilation. Receiver operating characteristic curves were created using treatment time points as the reference standard (before treatment and at 6Â months of treatment) and RDW and other traditionally used treatment efficacy markers (paCO2, HCO3, SRI-SS, SRI-RC and ESS values) as continuous predictors. Predictors were compared based on their ability to best discriminate between non-treated and treated patients based on their AUC values. ESS: Epworth Sleepiness Scale, HCO3: bicarbonate, paCO2: arterial partial pressure of carbon-dioxide, paO2: arterial partial pressure of oxygen, RDW: red cell distribution width, SRI-RC: Severe Respiratory Insufficiency Questionnaire Respiratory Complaints, SRI-SS: Severe Respiratory Insufficiency Questionnaire Summary ScoreBack to article page
