Performance and Discrimination Values of the Modified Objective Prognostic Score-B and Karnofsky Performance Status to Predict 2-Week Survival

Prognostic index	Prevalence n (%)	Sensitivity	Specificity	PPV	NPV	OA	AUROC (95% CI)
mOPS-B (≥1.5)	168 (53.0)	0.82	0.43	0.62	0.67	0.63	0.69 (0.63–0.74)
KPS (≤30)	168 (53.0)	0.77	0.38	0.58	0.60	0.59	0.65 (0.59–0.71)

AUROC, area under the receiver operating characteristic curve; KPS, Karnofsky Performance Status; mOPS, modified Objective Prognostic score; NPV, negative predictive value; OA, overall accuracy; PPV, positive predictive value.
