The impact of endoscopic submucosal dissection for gastric adenocarcinomas in the United States.

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
Background and Aims: Recent studies show promise for endoscopic submucosal dissection (ESD) in the US, but do not identify the potential impact of ESD among newly diagnosed gastric cancers. We utilize the Veterans Health Administration to identify cancers suitable for ESD, to define the role of ESD in the US. Methods: Retrospective cohort study using the Veterans Affairs Central Cancer Registry to identify patients with gastric cancer who underwent surgical resection from 1995-2018. TNM stage was used to categorize those who would meet absolute vs expanded indications for ESD. Primary outcome was lymph node status. Secondary analysis was performed with death as outcome. Results: Of 12,584 primary gastric cancers, 4,735 (37.6%) were non-metastatic gastric adenocarcinomas. Median age at diagnosis was 70.3 years, 4,676 (98.8%) male. 2,306 (48.7%) underwent surgical resection, of which 636 (27.6%) were T1 lesions or cancer in situ. Of these, 44 (6.9%) met absolute indications for resection, 99 (15.6%) met established expanded criteria, and 98 (15.4%) may meet expanded criteria. Half of all tumors in each group were proximal in location.Rate of lymph node positivity was: 4.5%; 95% CI:0.5-15.5% in absolute group; 8.1%; 95% CI:3.6-15.3% in expanded group; 13.3%; 95% CI:7.3-21.6 in those potentially meeting expanded criteria. Lymph nodes positivity was associated with death (HR 1.49; 95% CI:1.36-1.62, p<0.001). Conclusions: Less than 10% of T1 or
