GABA(A) receptor subunit expression in the guinea pig vestibular nucleus complex during the development of vestibular compensation.
Article in Experimental brain research, 2005. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
The aim of this experiment was to investigate whether vestibular compensation following unilateral vestibular deafferentation (UVD) is associated with changes in the expression of GABA(A) receptor subunits in the guinea pig vestibular nuclear complex (VNC) at 2, 10, and 30 h post-surgery. Using Western blotting, the alpha1 and gamma2 subunits (but not the beta2 subunit) were detected in the VNC of labyrinthine-intact animals. However, there were no significant differences in the protein expression of the alpha1 and gamma2 subunits within the ipsilateral or contralateral VNC at any time post-UVD compared to sham and anesthetic controls. Furthermore, UVD did not induce the expression of the beta2 protein. These results suggest that vestibular compensation in guinea pig, as in the rat, is not associated with changes in the protein levels of the GABA(A) receptor subunits alpha1, beta2, and gamma2 in the VNC. However, a limitation of this study is that the Western blotting technique can detect only changes that are larger than 30% and therefore small changes cannot be excluded.
