DNA mismatch repair is not disrupted in stage 0 colorectal cancer resected using endoscopic submucosal dissection.
Article in Oncology letters, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
The frequency of deficient mismatch repair (dMMR) or microsatellite instability-high colorectal cancer (CRC) is estimated to be ~15% of all patients with CRC; however, the patients reported are limited to surgical cases, and the frequency of patients exhibiting stage 0 disease is not considered, despite the currently increasing use of endoscopic techniques to cure a number of these patients. In the present study, the DNA MMR status for stage 0 patients with CRC treated using endoscopic submucosal dissection or endoscopic mucosal resection was analyzed via immunohistochemical staining of four types of proteins, namely MutL homolog 1 (MLH1), MutS homolog 2 (MSH2), MSH6 and PMS1 homolog 2 MMR system component, in adenocarcinoma specimens. Notably, none of the endoscopically resected specimens exhibited dMMR among the 41 patients diagnosed with stage 0 CRC. Since tumors harboring dMMR progress more rapidly than tumors with chromosomal instability, the present results highlight the importance of tumor resection during very early phases that exist before the promoter region of
