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

backgroundHearing loss is known to cause structural and functional abnormalities in the central auditory pathways. Interventions with hearing aids that amplify acoustic signals have been developed to combat hearing loss. However, little is known about how such devices may affect the brain and mitigate the progression of hearing loss. We hypothesized that timely intervention that amplifies acoustic signals would delay further progression of hearing loss by maintaining central auditory activity and neural structure.

methodTo that end, we provided eight weeks of acoustic stimulation tailored to compensate for subject-specific patterns of frequency loss in two mouse models of progressive hearing loss. We evaluated the effects of sound amplification on endbulb of Held anatomy at different ages of intervention in mice with early-onset (DBA/2) and late-onset (C57Bl/6) hearing loss.

resultsWe observed in both strains that endbulbs undergo rapid and progressive atrophy in untreated control subjects exposed to a baseline, unamplified, sound environment. In contrast, endbulb atrophy was significantly slowed in treated mice (

conclusionsThese data provide a possible explanation for how the brain benefits from sound amplification via hearing aid devices.
