Subtype-specific prognostic impact of TNIK in medulloblastoma.
Article in Journal of neuro-oncology, 2026. 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
purposeMedulloblastoma (MB) is the most common malignant pediatric brain tumor and comprises molecularly and clinically distinct subgroups with highly variable outcomes. While survival rates exceed 80% in some subgroups, others remain associated with substantially poorer prognosis and increased risk of relapse. Current treatment includes surgery, radiation, and chemotherapy, which can result in significant long-term treatment-related morbidity. These challenges highlight the need to identify novel biomarkers and potential therapeutic targets to improve risk stratification and enable more tailored treatment approaches. The Traf2- and Nck-interacting kinase (TNIK) is a regulator of Wnt/β-catenin signaling and has been implicated in the progression of several cancers, but its role in MB remains unclear.
methodsTNIK expression was evaluated using publicly available MB transcriptomic datasets, mass spectrometry based proteomic data, and immunohistochemical analysis of a MB tissue microarray. Associations between TNIK expression, molecular subgroups, overall survival, and established prognostic markers were assessed.
resultsTNIK expression was significantly enriched in Group 3 and Group 4 MBs compared to WNT and SHH subgroups. Survival analyses demonstrated distinct, subgroup-specific prognostic effects: high TNIK expression predicted inferior overall survival in Group 4, while in SHH tumors high TNIK expression levels were associated with improved outcome. These observations were supported by proteomic profiling.
conclusionThese findings indicate a subgroup-specific role for TNIK in MB biology and suggest its potential utility as a prognostic biomarker, particularly in Group 4 MBs.
