Overall survival and margin status in resected gastric stromal tumors.

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: Studies assessing gastrointestinal stromal tumors (GISTs) have found no survival differences based on margin status; however, small sample sizes, merged anatomic locations, and limited follow-up have been limitations. This study examined the impact of margin status on overall survival in a large national cohort of patients with resected gastric GISTs. Methods: Data on patients with gastric GISTs were abstracted from the National Cancer Database, with data collected over a 16-year period (2004-2020). Exclusion criteria included the presence of other primary tumors, unknown patient/tumor characteristics, macroscopic residual margins, metastasis at diagnosis, and prior chemotherapy. The cohort was stratified according to tumor size. R0 is defined as microscopically negative margin, and R1 is microscopically positive margin. Results: After exclusions, there were 8448 patients in the analysis cohort: 8221 (97.3%) had R0 resections, and 227 (2.7%) had R1 resections. On univariate analysis, tumor size ≤5 cm ( Conclusions: Congruent with prior studies, there was no difference in survival when comparing R0 with R1 resections in gastric GIST patients without metastasis over an extended follow-up period. These data may be helpful in assessing suitability for endoscopic resection for patients with gastric GISTs.
