Endoscopic mucosal resection versus endoscopic submucosal dissection for early colorectal cancer and precursor lesions: a retrospective study.
Article in Frontiers in medicine, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Objective: Endoscopic mucosal resection (EMR) and endoscopic submucosal dissection (ESD) are both used for early colorectal cancer (CRC) and precursor lesions, but optimal size thresholds and subgroup-specific outcomes remain unclear. This study aimed to investigate the efficacy and safety of EMR versus ESD for early CRC and precursor lesions. Patients and methods: This single-center retrospective study enrolled 101 patients with early CRC or precursor lesions. EMR ( Results: For lesions ≥20 mm, ESD achieved higher en bloc (91.2% vs. 71.4%, Conclusion: For lesions ≥20 mm, ESD provides superior resection outcomes, particularly for lesions ≥30 mm, but with higher complication rates, especially in the right colon. For lesions <20 mm, EMR is preferred. When en bloc EMR is not feasible, ESD should be prioritized over piecemeal EMR, particularly for lesions ≥30 mm.
