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

Mitochondria regulate cellular metabolism, signaling, and cell fate, yet the biological significance of coordinated mitochondrial genome transcription in lower-grade glioma (LGG) remains unclear. We integrated transcriptomic and clinical data from the TCGA and CGGA cohorts to investigate expression of the 13 mitochondrial DNA-encoded protein-coding genes (mtPCGs). Elevated expression of all mtPCGs was consistently associated with favorable molecular subtypes and prolonged overall survival (OS). Transcriptome-wide correlation and Gene Ontology analyses revealed a coordinated program enriched for synaptic signaling, neurotransmission, postsynaptic organization, and neuronal differentiation, accompanied by positive correlations with neuronal and synaptic markers and negative correlations with stemness and immune-associated markers. Although the mitochondrial transcriptional score was not independently associated with survival after adjustment for established clinicomolecular variables, it consistently marked biologically less aggressive tumors. Coordinated mitochondrial genome expression identifies a neuron-like transcriptional state associated with favorable LGG biology, revealing an unexpected link between mitochondrial transcription, synaptic identity, and glioma differentiation.
