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

The failure to clear dysfunctional mitochondria, cell death and inflammation have been linked in neurodegenerative disease, but their relationship and role in these conditions is not fully understood. Loss of Vps13d prevents clearance of mitochondria, and mutations in human VPS13D have been associated with neurological movement disorders. To investigate the relationship between mitochondrial health, inflammation and neurodegeneration, we created a conditional Vps13d-knockout mouse. Loss of Vps13d in excitatory neurons resulted in behavioral changes and neurodegeneration. Vacuolar protein sorting 13D (VPS13D) deficiency also caused mitochondrial ultrastructural defects and dysfunction in neurons followed by gasdermin E processing, cyclic GMP-AMP synthase (cGAS)-stimulator of interferon response cGAMP interactor (STING) signaling, microglial activation and cell death. Gasdermin E localization with mitochondria in Vps13d-mutant neurons was required for elevated extracellular mitochondrial DNA that promoted activation of microglia. Depletion of microglia suppressed cell death and behavioral phenotypes but not mitochondrial changes in the neuron-specific Vps13d-knockout model, indicating that microglia promote cell death in this model of neurodegenerative disease.
