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

Given the high prevalence of tinnitus and anxiety among patients, understanding the mechanisms that increase anxiety is crucial. Neuroligin 2 (NLGN2) is an anxiety-related protein that has received much attention in recent years. On the other hand, the Brain-Derived Neurotrophic Factor (BDNF) affects various neurotransmitter systems, neuropeptides, and intracellular signaling pathways. These are neurochemical systems that, if out of balance, could lead to anxiety behavior. This is the first study to investigate whether changes in protein expression in the amygdala nucleus are associated with high anxiety in tinnitus. After inducing and confirming tinnitus in rats using gap-prepulse inhibition of the acoustic startle (GPIAS) and Pre-pulse inhibition (PPI), the Elevated Plus Maze (EPM) and the Open Field Test (OFT) were used to assess anxiety levels in both groups. Subsequently, amygdala tissue samples were collected from both groups and analyzed for NLGN2 and BDNF protein expression. The GPIAS score decreased following sodium salicylate administration in the tinnitus group, while the PPI score did not change. Additionally, the tinnitus group exhibited higher anxiety levels than the control group in both behavioral tests. Moreover, NLGN2 protein expression was increased in the amygdala nucleus of sodium salicylate-induced tinnitus rats compared to controls, while BDNF protein expression was reduced. These findings suggest that increased NLGN2 and decreased BDNF protein levels in the amygdala nucleus contribute to tinnitus-related anxiety and identify these proteins as potential therapeutic targets for tinnitus.
