Fig. 4From: Differential contractile response of critically ill patients to neuromuscular electrical stimulationCorrelation and ROC curve for contractile response and SOFA. Relative contractile response between days 1 and 7 correlates with a SOFA score. b ROC curve for SOFA score in patients with adequate contractile response to neuromuscular electrical stimulation. SOFA = Sepsis-related Organ Failure Assessment; ROC = receiver operating characteristicsBack to article page
