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

Lower-grade (World Health Organization Grades II and III) gliomas vary widely in clinical behavior and are classified as astrocytic, oligodendroglial, or mixed. Anaplasia depends greatly on mitotic activity, with CDKN2A loss considered as the most common mechanism for cell cycle dysregulation. We investigated whether loss of the CDKN2A gene is associated with overall survival across pathologically and genetically defined glioma subtypes. After adjustment for IDH mutation, sex, and age, CDKN2A deletion was strongly associated with poorer overall survival in astrocytomas but not in oligodendrogliomas or oligoastrocytomas. Molecular classification of astrocytomas by IDH mutation, TP53 mutation, and /or ATRX loss of expression revealed that CDKN2A loss in IDH/TP53 mutated tumors was strongly associated with worse overall survival. CDKN2A loss in IDH mutated tumors with ATRX loss was only weakly associated with worse overall survival. These findings suggest that CDKN2A testing may provide further clinical aid in lower-grade glioma substratification beyond IDH mutation and 1p19q codeletion status, particularly in IDH/TP53 mutated astrocytomas.
