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

The establishment of cell fate and boundaries between cell types is an essential step in development and organogenesis. In the mammalian cochlea, a distinct boundary exists between a medial region of non-sensory cells and a lateral region of sensory cells. We report that Wnt4 and sFRP2 act in combination to modulate the sensory cell differentiation of the organ of Corti. The hair cell inhibitory effects of Wnt4 in the inner ear are mediated through the activation of the non-canonical Wnt/Calcium/PKC pathway. We show that Wnt4 stimulates the activation of PKC in the cochlea, and that the inhibition of PKC rescues the ectopic Wnt4 activity phenotype. Finally, we demonstrate that modification at a PKC target site on Atoh1 diminishes its ability to induce hair cell formation. Ultimately, we identify a new Wnt/Calcium/PKC non-canonical signaling pathway that is involved in proper hair cell and organ of Corti formation in the developing mammalian cochlea.
