Nomogram-based prognostic stratification for resectable gastric signet-ring cell carcinoma and adenocarcinoma: A retrospective cohort 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
backgroundGastric signet-ring cell carcinoma (GSRCC) is a more aggressive subtype of gastric cancer compared to gastric adenocarcinoma (GA), with an increasing incidence. However, the prognostic differences between these subtypes, particularly in resectable cases, remain unclear.
aimTo evaluate prognostic factors and develop a predictive model for GA and GSRCC patients undergoing curative resection.
methodsThis retrospective cohort study included patients with GA and GSRCC who underwent curative surgery at the National Cancer Center/Cancer Hospital, Chinese Academy of Medical Sciences, from 2011 to 2018. Propensity score matching (PSM) (1:1) balanced the baseline characteristics. Prognostic factors were identified using univariate and multivariate Cox and least absolute shrinkage and selection operator (LASSO) regression analyses. Model performance was evaluated through calibration curves, decision curve analysis (DCA), and time-dependent receiver operating characteristic curves. Subgroup analysis and Kaplan-Meier survival curves were generated.
resultsIn a cohort of 3027 patients, the GSRCC group was characterized by a significantly higher prevalence of individuals under 60 years of age, females, cases with poor differentiation, and early-stage (stage I) disease (all
conclusionThis study systematically compared resectable GA and GSRCC, revealing no overall survival difference. However, GSRCC demonstrated a significantly elevated mortality risk in subgroups stratified by age and tumor size. Multivariate analysis identified age, differentiation, tumor size, vascular invasion, and TNM stage as independent prognostic factors. The nomogram integrates clinicopathological features for precise risk stratification, surpassing traditional TNM staging.
