Notched noise reveals differential improvement in the neural representation of the sound envelope.
Article in Communications biology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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.
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
Precise temporal coding in auditory nerve fibers is crucial for sound localization and listening in noise. However, at higher sound levels, typical of everyday listening situations, temporal coding to the stimulus envelope is poor in fibers of the on-frequency channel, i.e., those tuned to the carrier stimulus. We predict that changes in cochlear gain improve temporal coding of the stimulus envelope differentially across frequency channels. Both auditory nerve fiber recordings (in Mongolian gerbils of either sex) and human psychophysics confirm that weak temporal coding at higher levels is improved when the target stimulus is presented in a spectrally flanking notched noise designed to reduce the cochlear gain. The proposed mechanism can help to explain the effect of cochlear gain loss, a known consequence of age- and noise-induced hearing loss, on everyday listening, such as problems with speech-in-noise perception and sound localization.
