Table 4 Per-adenoma miss rate by adenoma size

From: Impact of second forward-view examination on adenoma detection rate during unsedated colonoscopy: a randomized controlled trial

  Adenomas found on first forward-view examination Adenomas found on second forward-view examination Miss rate* (95% CI)
Numbers 22 6 0.214 (0.052–0.376)
 < 5 mm 15 4 0.211 (0.009–0.412)
5–9 mm 5 2 0.286 (−0.166–0.737)
 ≥ 10 mm 2 0 0.000 (0.000–0.000)
  1. CI confidence interval
  2. *Per-adenoma miss rate is the number of additional adenomas found on the second forward-view examination divided by the total number of adenomas
