1 · What the graph read from 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.

2 · The registry

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

aimsSessile serrated lesions (SSLs) have been increasingly recognized as precursors to colorectal cancer. Unlike adenoma detection rate (ADR), there is currently no agreed-upon benchmark for SSL detection rate (SSLDR), and data on factors that impact SSL detection are limited. We aimed to identify patient, endoscopist, and procedural factors associated with SSL and adenoma detection.

methodsWe used a single-center electronic endoscopy database to identify all patients ages ≥ 50 years who underwent outpatient screening colonoscopy from January 1, 2012, to June 30, 2018. Univariable Chi-square analysis was used to determine patient, endoscopist, and procedure-related factors associated with SSL or adenoma detection. We used logistic regression with generalized estimating equations, accounting for clustering by individual endoscopist, to determine factors independently associated with ADR and SSLDR.

resultsWe identified 10,538 unique patients who underwent colonoscopy performed by 28 endoscopists. Overall SSLDR was 2.2%, and overall ADR was 29.1%. On multivariable analysis, patient age, sex, BMI, smoking, endoscopist withdrawal time, and year of colonoscopy were independent predictors of ADR. Smoking and year of colonoscopy were independent predictors of SSLDR. Sub-optimal bowel preparation was inversely associated with SSL detection but not ADR.

conclusionsIn this large study of patients undergoing average-risk screening colonoscopy, overall SSLDR was low, indicating that methods for increasing SSLDR are needed. Our findings suggest that endoscopists may take into account risk factors for SSLs, such as smoking history, and recognize that the detection of such lesions, even more so than for adenomas, is dependent on optimal bowel preparation.
