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

Inner ear cochlear hair cells exhibit a highly specialized ciliary architecture that consists of a bundle of stereocilia responsible for mechanotransduction and, during development, a single kinocilium that governs hair bundle polarity. While the morphogenesis of stereocilia is being extensively characterized and many key molecules have been identified, the molecular mechanisms governing the formation and subsequent degeneration of the kinocilium remain largely unknown. Through immunohistochemical staining, we found that CCDC181, a microtubule-binding protein, is abundantly expressed in the postnatal cochlear hair cells and specifically localized to the kinocilium. To investigate its function in cochlear hair cell morphogenesis and auditory perception, we generated a Ccdc181 knockout mouse. Hair cell morphology was characterized by using immunostaining and electron microscopy, and auditory function was then evaluated by measuring auditory brainstem responses. Our data suggests that loss of CCDC181 has minimal effects on kinocilium morphogenesis, hair cell polarity, and normal hearing in mice.
