1 · What the graph read from it

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.

2 · The registry

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

introductionGlioblastoma is an aggressive primary brain tumor that invariably recurs despite maximal resection and chemoradiotherapy. Understanding the spatial and directional dynamics of recurrence is crucial for informing treatment strategies, yet prior studies have relied mainly on qualitative classification schemes.

methodsWe conducted a quantitative analysis of glioblastoma recurrence patterns using a two-pronged approach: voxel-based lesion mapping and vector analysis. Lesion distribution shifts between initial and recurrent tumors were statistically evaluated using anatomical labeling based on the AAL atlas. For directionality, we computed vectors from initial to recurrent lesion centroids and assessed their alignment with normative white matter fiber orientations derived from the Human Connectome Project.

resultsLesion mapping revealed a significant posterior shift of distribution in recurrence, particularly involving the parietal lobe. Vector analysis demonstrated that the recurrence vectors exhibited significant directional concordance with local white matter trajectories, as indicated by high mean absolute correlation coefficients (0.60 ± 0.23). These findings suggest that white matter pathways may guide tumor cell migration during recurrence.

conclusionThis study introduces a novel quantitative framework for assessing the spatial and directional features of glioblastoma recurrence. Our integrative analysis highlights the influence of structural brain connectivity on tumor spread and may ultimately contribute to refining initial treatment planning strategies.
