ROC curve analysis for BMI and SOFA score associated with f-Carnitine reduction at day 14. Each plot depicts a relationship between sensitivity on the x-axis and 100-specificity on the y-axis. The cutoff value of BMI (a) was defined as 19.5, with the ROC curve depicting area under the curve (AUC) of 0.81 (95% confidence interval 0.66–0.97). A significant cutoff value was not defined for SOFA score (b) (tentative cutoff value 8.5; AUC = 0.57, 95% confidence interval 0.35–0.78)
