VIS is an independent predictor of PICU mortality in patients with malignancy. (a) The receiver operating characteristic curve of the vasoactive–inotropic score (VIS) in predicting the survival status in patients with malignancy. The sensitivity is 0.606, specificity is 0.889, accuracy is 0.733, positive predictive value is 0.870 and negative predictive value is 0.649. (b) the Kaplan–Meier curve of the PICU mortality in the subgroups stratified by the VIS (cutoff value, 137.5) in patients with malignancy
