Boston Bowel Preparation Scale scores provide a standardized definition of adequate for describing bowel cleanliness.
Observational study in Gastrointestinal endoscopy, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to 4 registered trials, which are not on this map. Cited by 96 papers, 5 of them syntheses 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.

Abstract
backgroundEstablishing a threshold of bowel cleanliness below which colonoscopies should be repeated at accelerated intervals is important, yet there are no standardized definitions for an adequate preparation.
objectiveTo determine whether Boston Bowel Preparation Scale (BBPS) scores could serve as a standard definition of adequacy.
designCross-sectional observational analysis of colonoscopy data from 36 adult GI endoscopy practices and prospective survey showing 4 standardized colonoscopy videos with varying degrees of bowel cleanliness.
settingThe Clinical Outcomes Research Initiative. PATIENTS: Average-risk patients attending screening colonoscopy.
interventionsColonoscopy. MAIN OUTCOME MEASUREMENTS: Recommended follow-up intervals among average-risk, screening colonoscopies without polyps stratified by BBPS scores.
resultsWe evaluated 2516 negative screening colonoscopies performed by 74 endoscopists. If the BBPS score was ≥2 in all 3 segments (N = 2295), follow-up was recommended in 10 years in 90% of cases. Examinations with total BBPS scores of 3 to 5 (N = 167) had variable recommendations. Follow-up within 1 year was recommended for 96% of examinations with total BBPS scores of 0 to 2 (N = 26). Similar results were noted among 167 participants in a video survey with pre-established BBPS scores. LIMITATIONS: Retrospective study.
conclusionBBPS scores correlate with endoscopist behavior regarding follow-up intervals for colonoscopy. A total BBPS score ≥6 and/or all segment scores ≥2 provides a standardized definition of adequate for 10-year follow-up, whereas total scores ≤2 indicate that a procedure should be repeated within 1 year. Future work should focus on finding consensus for management of examinations with total scores of 3 to 5.
