Longitudinal Vibrations in the Organ of Corti are Limited to Its Core.

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
purposeThe goal of this research was to determine where in the organ of Corti (ooC) sound-induced, longitudinal vibrations occur, and how they depend on the health of the cochlea.
methodsSound-evoked vibrations of the ooC in the cochlea's middle turn of adult anesthetized gerbils were measured using optical coherence tomography (OCT). Vibratory responses, evoked with acoustic tone complexes, were recorded at multiple, closely spaced (20 μm), tonotopic locations which changed the "viewing angle" of the vertical OCT beam re. the longitudinal motion. After spatial alignment of the responses, within-ooC regions exhibiting sound-induced longitudinal motion were identified from a conspicuous 180° phase flip.
resultsLongitudinal motion was restricted to the outer hair cells (OHC), Deiters' cells and the tunnel of Corti (i.e., the ooC's "core"). They were frequency and level-independent but did depend on the ear's metabolic state; after death, they disappeared.
conclusionThere can be little doubt about the presence of longitudinal motions within the cochlea. Their disappearance postmortem and spatially restricted occurrence suggest these longitudinal vibrations arise from active processes within the OHC. Whether this involves cycle-by-cycle feedback or some other, as-of-yet undetermined, mechanism remains to be resolved.
