Outcomes After Surgical Resection Differ by Primary Tumor Location for Metastatic Gastrointestinal Stromal Tumors (GISTs): a Propensity Score Matching Population Study.

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
purposePrimary tumor location has been identified as an important prognostic factor among patients with gastrointestinal stromal tumors (GISTs). The purpose of this study is to identify how primary tumor location may affect outcomes after resection for patients with metastatic GISTs.
methodsPatients with GISTs and distant metastases at diagnosis were identified in the Surveillance Epidemiology and End Results (SEER) database. Patients that underwent surgery were matched to patients that did not undergo surgery using propensity score matching (PSM) analysis.
resultsAfter PSM, 570 patients were identified (males 334 [58.6%], females 236 [41.4%], age 62 ± 13.9 years). Gastric tumors constituted the majority (325 [57%]), followed by small intestinal (136 [23.9%]), colorectal (19 [3.3%]), and retroperitoneal/peritoneal tumors (23 [4%]). Median follow-up was 25.5 months (95% CI 23-29 months). Undergoing surgery was associated with improved disease-specific survival (DSS) on both univariate (median not reached vs. 51 months, p < 0.001) and multivariate analyses (HR 4.98, 95% CI 2.23-11.12, p < 0.001). A sub-analysis of patients with gastric GISTs showed that undergoing surgery was the only significant factor associated with improved DSS (median not reached vs. 39 months, p < 0.001, HR 2.95, 95% CI 1.92-4.53). In contrast, undergoing surgery was not associated with improved survival for small intestinal, colorectal, or retroperitoneal/peritoneal tumors.
conclusionsSurgery for gastric metastatic GISTs is associated with improved survival. No discernible benefit after surgical resection was identified for patients with small intestinal, colorectal, retroperitoneal, or peritoneal metastatic GISTs.
