Lymph Node Yield and Lymph Node Ratio for Prognosis of Long-Term Survival in Gastric Carcinoma.
Article in Cancers, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
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
backgroundLymphadenectomy is a fundamental part of surgical strategy in patients with gastric cancer. Lymph node (LN) status is a key point in assessment of prognosis in gastric cancer. The LN ratio (LNR)-number of positive LNs/number of sampled LNs-offers a new approach for predicting survival. The aim of the study was to find factors affecting LN yield and the impact of LNR on 5-year survival.
methodsProspective multicenter quality assurance study. Only LN-positive patients were included in the LNR calculations.
results4946 patients from 149 hospitals were enrolled. The inclusion criteria were met by 1884 patients. Patients were divided into two groups: Group 1 (<16 LN), 456 patients and Group 2 (≥16 LN), 1428 patients. The multivariate analysis found G2 (OR 1.98; 95%CI 1.11-3.54), G3 (OR 2.15; 95%CI 1.212-3.829), UICC-stage II (OR 1.44; 95%CI 1.01-2.06) and III (OR 1.71; 95%CI 1.14-2.57), age < 70 (OR 1.818 95%CI 1.19-2.78) and female gender (OR 1.37; 95%CI 1.00-1.86) as independent factors of ≥16 LN yield. Patients with a LNR ≥ 0.4 have a lower probability of survival (
conclusionLong-term survival is directly related to adequate lymphadenectomy. LNR could be superior to pN-stage for estimating survival and adds remarkable nuances in prognosis compared to UICC-stage. LNR also appears valid, even in the case of insufficient LN yield.
