Incidence of interval colorectal cancer attributable to an endoscopist in clinical practice.
Article in Gastrointestinal endoscopy, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 11 papers, 1 of them a synthesis that pooled it.
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
BACKGROUND AND
aimsEndoscopists who encounter an interval colorectal cancer (I-CRC) may be concerned about the implications because I-CRCs may represent a lapse in colonoscopy quality and a missed opportunity for prevention. We wanted to determine the I-CRC rate per colonoscopy examination and to examine the effect of colonoscopy volume and adenoma detection rate (ADR) on the number of I-CRCs attributable to an endoscopist.
methodsWe determined the rate of I-CRC diagnosis per outpatient colonoscopy examination by measuring the incidence of CRC diagnosis in practice and by assessing, via literature review, the percentage of cancers that are interval. We also estimated the number of attributable I-CRCs as a function of ADR and colonoscopy volume.
resultsAmong 93,562 colonoscopies performed in 2013 to 2015 by 120 physicians in 4 diverse U.S. medical centers, 526 CRCs were diagnosed (.6%). Of 149,556 CRCs in the published literature, 7958 were I-CRCs (5.25% ± .94%). With rates of .6% (CRC per colonoscopy) and 5.25% (I-CRC per CRC), the rate of I-CRC is 1 per 3174 colonoscopies (95% confidence interval, 1 per 2710 to 1 per 3875). An endoscopist at the median of outpatient colonoscopy volume (316/year) in the lowest ADR quintile of detection (7%-19%) would have an I-CRC attributed every 8.2 years, or 4.2 I-CRCs in a 35-year career, versus every 16.7 years, or 2.0 I-CRCs in a 35-year career, for an endoscopist in the highest ADR quintile (33%-52%).
conclusionsAn average-volume endoscopist will have 2 to 4 attributable I-CRCs in a 35-year career, but the frequency will vary depending on colonoscopy volume and ADR.
