Real-World Performance of FIT Triage for Symptomatic Colonoscopy: Analysis of the UK National Endoscopy Database (NED).
Article in Alimentary pharmacology & therapeutics, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundThe UK has adopted faecal immunochemical testing (FIT) to triage symptomatic colonoscopy referrals.
objectiveQuantify diagnostic yield and independent effects of FIT, age, sex and symptoms on polyp and cancer detection in symptomatic colonoscopy.
designNationwide analysis of prospectively collected colonoscopy reports (June 2023-August 2025) from the National Endoscopy Database. Symptomatic procedures, including iron-deficiency anaemia (IDA), were identified and diagnostic yields calculated. Mixed-effects logistic regression estimated adjusted odds ratios (aORs) with age, sex, symptom group and FIT. Post-estimation margins modelled cancer yield by age, FIT and symptoms.
resultsAnalysis of 447,109 symptomatic colonoscopies, with FIT recorded in 202,219 (45.2%). Overall cancer yield was 1.9% (95% CI, 1.8-1.9). Cancer yield was 3.8% (95% CI, 3.7-3.9) in FIT ≥ 10, including 2.5% (95% CI, 2.3-2.7) at age 40-49 and 0.6% (95% CI, 0.5-0.7) at age 16-39; yield in FIT < 10 was 0.3% (95% CI, 0.2-0.3). FIT concentration showed a strong, graded association with cancer risk, weaker association with large polyps, and minimal association with small polyps. IDA was associated with higher cancer risk versus rectal bleeding (aOR 2.2, 95% CI, 2.0-2.3; p < 0.01). With FIT < 10, cancer yield exceeded 1% only in IDA patients aged > 80 and remained < 0.5% otherwise. A model combining FIT, age, and IDA detected > 94% of cancers while reducing colonoscopy demand by > 40%.
conclusionThis national analysis demonstrates the superiority of FIT-based triage over symptom-based referral, with FIT ≥ 10 identifying high-risk patients, including those aged 40-49, while FIT < 10 indicated very low risk.
