FGF13 prevents age-related hearing loss by protecting spiral ganglion neurons and ribbon synapses from injury.

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
Age-related hearing loss (ARHL) is the most common sensorineural hearing loss, and the dysfunction of spiral ganglion neurons (SGNs) and ribbon synapses plays a crucial role in the pathogenesis. The fibroblast growth factor 13 (FGF13) is considered to be associated with neuronal survival and synaptic transmission. However, whether FGF13 is involved in degeneration of SGNs and ribbon synapses, the typical changes of ARHL, is still unknown. Firstly, the expression of FGF13 mRNA and protein, was all dramatically decreased in the SGNs of aged mice, accompanied by impaired SGNs and ribbon synapses. More importantly, specific upregulation of FGF13 in SGNs significantly reduced hearing threshold, improved wave I amplitude, and alleviated loss of SGNs as well as ribbon synapses. Furthermore, the proteomic analysis and verification results suggested that the decrease of FGF13 induced the loss of SGNs and ribbon synapses partly by regulating the ORC1. Taken together, our data revealed that FGF13 might protect SGNs and ribbon synapses by regulating the expression of ORC1, which could provide a new idea and targets for the prevention and treatment of ARHL.
