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

Alterations in excitation/inhibition (E/I) balance and changes in motor neurons (MN) activity may contribute to MN vulnerability in ALS. The balance of pathogenic versus adaptive changes occurring in inhibitory synapses and affecting E/I balance remain unclear. Confocal microscopy of MN from P45 male SOD1G93A mice reveal downregulated GlyR but upregulated GABAR clusters at inhibitory synapses. GlyR and GABAR respond to PSAM and DREADD chemogenetic alterations of MN excitability, with increased activity driving increase in inhibitory clusters. An E3 ligase-conjugated intrabody (GFE3) degrades Gephyrin, decreases GABAR and GlyR clusters, increases net activity, and downregulates disease markers. However, simultaneous decrease of inhibition and increased activity by actPSAM and GFE3 shows no net beneficial effects on disease markers. Thus inhibitory synapses are involved in the early phases of ALS pathogenesis and respond to persistent homeostatic loops, and their suppression delivers a net activity increase, offering potential benefits on disease pathways.
