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
introductionBowel bubbles are one of the key factors influencing the quality of colonoscopy. We aimed to evaluate the density of luminal bubbles in colonoscopy and compared oral sulfate solution (OSS) with 2L polyethylene glycol and electrolyte solution with ascorbic acid (PEG) in a same-day preparation.
methodsThis was a retrospective multicenter study. A total of 162 patients (45 OSS and 117 PEG) who underwent colonoscopy with bubble assessment between June and September 2024 were analyzed. The rate of bubbles by location and the risk factors for severe bubbles in the proximal colon were examined. Additionally, the comparisons of bubbles and polyp detection in OSS and PEG after propensity-score matching were performed using an original score named as bowel bubble score of colonoscopy (BBS-C; score 0: none-score 3: severe).
resultsAmong 162 cases, the rates of severe bubbles were 16.0% in the proximal colon and 9.9% in the distal colon (p = 0.098). In the multivariate analysis of risk factors for severe bubbles in the proximal colon, good preparation was positively associated with severe bubbles (OR: 4.878; 95% CI 1.33-20.0; p = 0.017), with poor preparation as the reference. After matching, the rates of severe bubbles in the proximal colon between the OSS and PEG groups were 11.1% vs. 6.7% (p = 0.470).
conclusionThe rates of bubbles in each segment were examined by BBS-C, and good bowel preparation was a risk factor for proximal severe bubbles. There was no significant difference regarding severe bubbles between OSS and PEG.
