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

Introduction: Underwater endoscopic mucosal resection is an alternative technique to conventional endoscopic mucosal resection, with potential advantages in efficacy and safety. In Latin America, there are few reports on its application. Objective: To evaluate the effectiveness, feasibility, and safety of underwater endoscopic mucosal resection for non-pedunculated colorectal lesions in a Latin American series. Materials and Methods: A prospective, observational study conducted between December 2023 and December 2024. Consecutive patients with non-pedunculated colorectal lesions ≥ 10 mm without endoscopic signs of deep submucosal invasion were included. Demographic data, lesion characteristics, technical success, resection type, histological findings, complications, and six-month recurrence were recorded. Results: Sixty patients with 67 lesions were included. The mean lesions size was 16.7 mm. The most common location was the right colon (56.7%), and the predominant morphology was granular LST (59.7%). Technical success was 100%, and en bloc resection was achieved in 91% of cases (96.5% for lesions ≤ 20 mm). Histology showed: tubular adenomas (47.7%), tubular adenomas with high-grade dysplasia (16.4%), serrated adenomas without dysplasia (4.4%), serrated adenomas with low-grade dysplasia (16.4%), and intramucosal adenocarcinomas (5.9%). Intraprocedural bleeding occurred in 11.9% and delayed bleeding in 2.9%, with no perforations. A significant association was found between lesion size and resection type (p < 0.001). Piecemeal resection was more frequent in lesions > 20 mm (RR 12.88; 95% CI: 2.75 - 60.43). At six months, control colonoscopy was performed in 85.1% of cases, with no evidence of recurrence. Conclusions: Underwater endoscopic mucosal resection proved to be effective, safe, and feasible, with high en bloc resection rates, and low rate of complications and absence of short-term recurrence.
