Figure 1From: A decision-analytic approach to define poor prognosis patients: a case study for non-seminomatous germ cell cancer patientsBenefit and harm of treatment, expressed on the same scale.

Net benefit occurs only when risk is above the threshold. Adapted from Glasziou & Irwig (1995).Back to article page
