F-actin in the cuticular plate and junctions of auditory hair cells is regulated by ADF and cofilin to allow for normal stereocilia bundle patterning and maintenance.

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, which convert sound-induced vibrations in the inner ear into neural signals, depend on multiple actin populations for normal function. Stereocilia are mechanosensory protrusions formed around a core of linear, crosslinked F-actin. They are anchored in the cuticular plate, which predominantly consists of randomly oriented actin filaments. A third actin population is found near hair cell junctions, consisting of both parallel and branched filaments. Actin depolymerizing factor (ADF) and cofilin-1 (CFL1) proteins disassemble actin filaments and are required to regulate F-actin in stereocilia, but their effect on cuticular plate and junctional actin populations is unclear. Here, we show that loss of ADF and CFL1 disrupts the patterning of stereocilia into orderly bundles and that this phenotype correlates with defective development of the cuticular plate and junctional actin populations. ADF/CFL1 continue to regulate these actin populations in mature cells, which is necessary for long-term maintenance of hair cell morphology.
