Surgical Resection Enhances Survival in Patients With Liver Metastases From Gastric Cancer: A Population-Based, Case-Control Study.
Article in Health science reports, 2024. 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
Background and Aims: Gastric cancer with liver metastases (GCLM) is a challenging condition that significantly reduces long-term survival rates, but recent advancements in surgical techniques have shown promise. This study aims to comprehensively evaluate the impact of surgical resection on survival rates in GCLM patients. Methods: We conducted a population-based analysis utilizing the SEER database for patients diagnosed with GCLM between 2010 and 2015. Overall survival (OS) was compared between patients who underwent cancer-directed surgery (CDS) and those who did not. The overlap weighting method based on lasso regression with penalty factors was employed to minimize selection bias. Survival outcomes were compared using Kaplan-Meier curves and Cox proportional hazards models, with subgroup analyses to further explore the effects of surgery among patients. Results: A total of 3694 patients with GCLM were identified. Of those, 354 (9.58%) patients underwent CDS. After propensity score adjustment, The median OS was significantly higher in the surgical resection group (12 months, 95% confidence interval (CI) 11-16) compared to the nonresection group (6 months, 95% CI: 5-6). Cox regression analysis revealed a substantial improvement in OS for the surgical resection group, with a hazard ratio (HR) of 0.562 (95% CI: 0.482-0.656), including patients with adverse conditions. Conclusions: The analysis demonstrated a clear association between surgical resection and enhanced OS in GCLM patients. Nevertheless, further research endeavors should be undertaken to identify specific prognostic factors that aid in the selection of optimal candidates for surgical resection.
