Prognostic value of preoperative Prognostic Nutritional Index (PNI) versus Neutrophil Lymphocyte Ratio (NLR) in gastric-cancer patients: a retrospective cohort study.
Article in BMC cancer, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundSystemic inflammation and nutritional issues have been regarded as cancer complications. As indicators of systemic inflammatory responses, neutrophil/lymphocyte ratio (NLR) and prognostic nutritional index (PNI) have been recommended to be used in the prediction of certain cancer-related clinical complications. The purpose of this study is to investigate the effects of PNI and NLR on the prognosis of gastric cancer.
methodsFrom 2010 to 2018, 559 gastric-cancer patients consecutively undergoing radical surgery were involved in this study. A receiver operating characteristic (ROC) analysis was conducted to determine the optimal cut-off values of PNI and NLR. Using these cut-off values, we categorized the patients into high and low PNI/NLR groups, with clinical characteristics of these two groups compared and analyzed.
resultsLow PNI and high NLR were both associated with worse OS in univariate analysis (P < 0.001 for both). In multivariate analysis, low PNI remained an independent prognostic factor for poor OS (HR = 1.502, 95%CI: 1.135-1.987, P = 0.004), while NLR did not demonstrate independent prognostic significance in this cohort.
conclusionIn patients with resectable gastric cancer, preoperative PNI was identified as an independent prognostic factor for overall survival, while NLR did not show independent prognostic value in this cohort. These findings suggest that PNI may be useful in preoperative risk assessment and patient counseling. Further studies are needed to validate these results and directly compare the prognostic performance of PNI and NLR.
