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

introductionRecent studies have demonstrated that the protective effect of colonoscopy against colorectal cancer is lower in the proximal colon. Proximal serrated polyps, including sessile serrated adenomas and proximal hyperplastic polyps, can be frequently missed and pose a risk of interval cancers.

aimTo investigate the overall adenoma detection rate (ADR) and the proximal serrated polyp detection rate (PSPDR) among academic gastroenterologists, community gastroenterologists, and colorectal surgeons from a single institution, all of whom have received formal training in colonoscopy during their fellowship.

methodsAll complete screening colonoscopies for patients aged 50 or older with a good to excellent bowel preparation performed by different endoscopists at Medstar Washington Hospital Center (Washington, DC) from July 2015 to December 2017 were reviewed. Pathology reports of the resected polyps were manually reviewed.

resultsA total of 2850 screening colonoscopies meeting the inclusion criteria were performed by 18 endoscopists (6 academic, 7 community, and 5 colorectal surgeons). There was no significant difference in the mean ADR among the three groups of endoscopists: academic gastroenterologists, community gastroenterologists, and colorectal surgeons (40.3% vs 36.0% vs 39.6%, respectively). However, academic gastroenterologists had a significantly higher PSPDR compared to community gastroenterologists or colorectal surgeons (12.3% vs 5.4% vs 4.5%, respectively, ANOVA p = 0.006).

conclusionOur novel data show that academic gastroenterologists had a significantly higher PSPDR compared to community gastroenterologists or colorectal surgeons despite a comparable overall ADR among the three groups. PSPDR may be considered as an important quality indicator for colonoscopy, apart from ADR.
