COL, colonoscopy; SIG, sigmoidoscopy; DCBE, double contrast barium enema; FOBT, fecal occult blood test. Ellipses indicate no data (incremental days or life gained and incremental CE ratio were not calculated for these strategies because they were dominated or extended dominated).

Exchange rate: 1200 Korean won for one US dollar.
Incremental CE ratio (won/year) = Incremental cost per person/Incremental days of life gained×365 d.
Dominated strategy is a strategy that is more or equally costly and less effective than a competing strategy.
