What is the most cost-effective strategy to screen for second primary colorectal cancers in male cancer survivors in Korea?

Table 4 Two-way sensitivity analysis on cost-effectiveness of 2nd primary colorectal cancer screening by compliance of screening and age of Korean male cancer survivors for starting screening

Age for starting screening	Compliance of 2nd colorectal cancer screening = 60%				Compliance of 2nd colorectal cancer screening = 80%				Compliance of 2nd colorectal cancer screening = 100%
	Non-dominated strategy	Lifetime cost per person (dollar)1	Life expectancy (yr)	Incremental C/E2 (dollar)1 per life-year gained	Non-dominated strategy	Lifetime cost per person (dollar)1	Life expectancy (yr)	Incremental C/E2 (dollar)1 per life-year gained	Non-dominated strategy	Lifetime cost per person (dollar)1	Life expectancy (yr)	Incremental C/E2 (dollar)1 per life-year gained

COL10: Colonoscopy every 10 years; COL5: Colonoscopy every 5 years; COL3: Colonoscopy every 3 years. Dominated strategy is a strategy that is more or equally costly and less effective than a competing strategy.
