Odds ratios (ORs) for the probability of detection of colorectal neoplasia in screened individuals which FIT and FS in comparison with gFOBT

Advanced neoplasia OR, (CI)Colorectal cancer OR, (CI)
FIT2.0 (1.3 to 3.2)1.8 (0.7 to 4.7)
FS7.0 (4.6 to 10.7)2.2 (0.8 to 6.3)
  • Advanced neoplasia: adenoma ⩾10 mm, villous component (⩾25% villous) or high-grade dysplasia; colorectal cancer.

  • CI, confidence interval; FIT, immunochemical faecal occult blood test; FS, flexible sigmoidoscopy; gFOBT, guaiac-based faecal occult blood test.
