Super-resolution mapping of the ankle link proteins ADGRV1 and PDZD7 in developing auditory hair cells.

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
Auditory hair cells convert mechanical stimuli into electrical signals. Inner hair cells (IHCs) serve as primary sensory receptors, while outer hair cells (OHCs) function as cochlear amplifiers. During development, the G-protein-coupled receptor ADGRV1, along with usherin, whirlin, and PDZD7, interacts at the base of stereocilia to form the transient ankle-link complex. The long extracellular domain of ADGRV1 bridges adjacent stereocilia, while its intracellular domain binds to whirlin and PDZD7. Using STED nanoscopy on juvenile mouse hair cells, we mapped the spatial distribution of ADGRV1 regions and PDZD7, revealing highly asymmetric localization patterns within stereocilia rows and between IHCs and OHCs. These distinct distributions reflect tightly regulated subcellular targeting of the proteins, which show strong colocalization. Interestingly, while the extracellular portion of ADGRV1 is no longer detectable after postnatal day 12, the GPCR domain persists until P21, suggesting that ADGRV1 may also play a signaling role beyond its scaffolding function.
