Table 3 The proportion of sampled cases that are considered cost-effective at different thresholds and varying cost of proton therapy for the whole patient cohort (for the patient where proton therapy is least likely to be cost-effective on the left-hand side of the parentheses, and most likely to be cost-effective on the right-hand side)

From: Individualized quality of life benefit and cost-effectiveness estimates of proton therapy for patients with oropharyngeal cancer
