Development of a Prognostic Nomogram for Overall Survival in Gastric Cancer Patients Who Underwent Adjuvant Chemoradiotherapy.

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
purposeThe aim of this study was to identify prognostic factors influencing overall survival (OS) in patients with gastric cancer treated with adjuvant chemoradiotherapy (CRT) and to develop a predictive model.
methodsWe retrospectively evaluated 245 non-metastatic gastric cancer patients who received adjuvant CRT or radiotherapy from 2010 to 2020. Survival analyses were performed using the Kaplan-Meier method. Prognostic factors were identified through univariate and multivariate Cox regression analyses. A nomogram was constructed based on significant predictive factors for OS, including lymph node ratio, T classification, tumor location, and local recurrence.
resultsThe median follow-up duration was 41.5 months (range, 6-144.8 months). The 2- and 5-year OS and progression-free survival were 77% and 53% and 64% and 49%, respectively. In multivariate analysis, tumor location (distal vs. proximal), pT classification (pT1-2 vs. pT3-4), lymph node ratio (< 0.18 vs. ≥ 0.18), and presence of local recurrence were independent prognostic factors for OS. The optimal cut-off value for the total nomogram score predicting OS was 116 points. Patients with < 116 points had 2- and 5-year OS rates of 87% and 73%, respectively, compared to 67% and 30% for those with ≥ 116 points.
conclusionA nomogram was constructed incorporating lymph node ratio, T classification, tumor site, and local recurrence for gastric cancer patients receiving adjuvant CRT. Patients with a total score below 116 demonstrated higher survival rates. This nomogram may aid in defining optimal follow-up intervals.
