Pediatric brain tumor patients display altered immune activation and reduced lymphopoiesis at the onset of disease.
Article in NPJ precision oncology, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Optimal immune function is crucial in preventing cancer development and growth and for the success of anti-cancer therapies. Here, we characterized the peripheral immunological status of 83 steroids-naïve pediatric patients with central nervous system neoplasia at the disease onset. Tumors were classified into low-grade gliomas (LGG), high-grade gliomas (HGG), medulloblastoma, and other tumors. We revealed that glioma patients showed an altered lymphocyte pool. T-cells of HGG patients shifted from naïve to effector memory phenotype. LGG patients exhibited T-cell central memory expansion and higher T-cell activation. Interestingly, HGG patients displayed reduced thymic function. Furthermore, LGG and HGG patients showed reduced activated B-cells and suboptimal B-cell formation. Our data demonstrate that glioma patients have reduced lymphopoiesis at the disease onset, which could contribute to the systemic lymphopenia characterizing these patients. This study offers novel insights into the immunological status of brain tumor patients which may help in designing more effective treatments.
