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
introductionUnderwater endoscopic mucosal resection (uEMR) represents an alternative to conventional EMR for resection of sessile colorectal polyps. We aimed at assessing the efficacy and safety of uEMR for sessile colorectal polyps.
methodsA retrospective analysis of endoscopy database was done for patients who underwent uEMR for sessile colorectal polyps more than 10 mm in size without any features of sub-mucosal invasion from two tertiary care centres in western India between January 2021 and June 2023. Exclusion criteria were other modes of endoscopic resection. Primary outcome was rate of en bloc resection. Secondary outcomes were complete resection rate, adverse events and recurrence rate.
resultsDuring the study period, 159 patients with 261 lesions met the study inclusion. Mean lesion size was 1.935 ± 0.71 cm with most lesion located in the rectum (75, 28.73%) followed by sigmoid colon (69, 26.43%). Most lesions had a Paris 0-Is morphology (192, 73.56%). Japan NBI Expert Team (JNET) IIa pattern was seen on narrow band imaging (NBI) in 221 (84.67%) lesions. Complete resection was achieved in 98.46% lesions (257/261). En bloc resection was achieved in 91.82% (236/257) lesions. Complications were seen in 6.8%, all of which were managed endoscopically. Recurrence was seen in 3.1% of polyps on follow-up.
conclusionuEMR is a safe and efficacious technique for endoscopic resection for sessile colorectal polyps with high rates of en bloc resection for polyps more than 10 mm size.
