Prognostic relationship of peripheral blood-immune inflammatory index (C-PLAN) in patients with high-grade glioma.
Article in BMC cancer, 2025. 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
objectiveThe C-PLAN index, which comprehensively considers inflammation, nutritional status, tumor grade/metabolism, and functional status, has been proven to be an effective predictor of various cancers. However, its application in patients with high-grade glioma (HGG) has not been studied. Therefore, this study aimed to analyze the impact of the C-PLAN index on the survival of HGG patients.
methodsThis study included 140 HGG patients who underwent postoperative radiotherapy/radiochemotherapy between April 2011 and May 2024. Patient medical records were retrospectively analyzed. Demographic and clinical data (IDH status, surgical procedure, histopathological type, Karnofsky Performance Status) were analyzed. Overall survival (OS) and progression-free survival (PFS) were evaluated using Kaplan–Meier survival curves and Cox regression analysis.
resultsData from 140 HGG patients were analyzed. The median survival was 12 months (IQR 25–75: 7–21 months). In univariate analysis, IDH status (χ2(1) = 11.17, p < 0.001), KPS score (χ2(1) = 29.57, p < 0.001), and C-PLAN index (χ2(1) = 8.83, p = 0.003) were significant predictors of OS. In the multivariate analysis, IDH status (p = 0.003, HR = 3.23 [95% CI: 1.47–7.09]) and KPS score (p < 0.001, HR = 2.68 [95% CI: 1.58–4.52]) remained significant predictors of OS, whereas the C-PLAN index was not significant (p = 0.17, HR = 0.69 [95% CI: 0.404–1.18]). DISCUSSION: This is the first study to investigate the impact of the C-PLAN index on overall OS in patients with HGG. The results showed that in univariate analysis, IDH status, Karnofsky Functional Status Score (KPS), and the C-PLAN index were significant predictors of OS in HGG patients. In multivariate analysis, all factors except the C-PLAN index were also significant. Further research is needed to confirm these findings.
