Cost-effectiveness analysis of proton beam therapy for treatment decision making in paranasal sinus and nasal cavity cancers in China

Table 2 One-way sensitivity analysis of influential parameters affecting the incremental cost-effectiveness ratio of the base case

Parameters^a	Base Value	Expected Value	With 3 Different WTP Thresholds
Parameters^a	Base Value	Expected Value	$30,828 / QALY^b	$50,000 / QALY	$100,000 / QALY
The probability of IMPT eradicating cancer	0.9	Minimum	0. 859	0.809	0.769
The probability of IMRT eradicating cancer	0.73	Maximum	0.771	0.821	0.861
The cost of IMPT ($)	50,000	Maximum	61,899	93,508.3	175,945.3
