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
Stress plays a pivotal role in anxiety-like disorders and cognitive decline. The present study investigated the potential effects of prior royal jelly supplementation and environmental enrichment against stress-induced anxiety-like behaviors, serum corticosterone, hippocampal brain-derived neurotrophic factor (BDNF) levels, and cognitive performance deficits in stressed rats. Male Wistar rats were randomly devised into 8 experimental groups. Rats were subjected to royal jelly (200 mg/kg) via oral gavage, standard environmental enrichment, or combination all for 14 days and control rats received saline in the same period of time. Stress induction was done on the 7th day of treatments by exposure to the restrainer under 10°C. Then open field, elevated plus maze, and inhibitory passive avoidance memory tests were used to explore emotional-cognitive behaviour. Also, corticosterone levels, and hippocampal BDNF expression were measured. Stress resulted in an increase in the serum corticosterone levels, anxiety-like behaviors, and decreased hippocampal BDNF expression which reversed by environmental enrichment and royal jelly treatments. Remarkably, the combined treatment exerts a more pronounced effect on the aforementioned outcomes. Our study strongly proposes a novel emerging therapeutic approach through nutritional interventions, emphasizing the potential of these treatments to mitigate stress-induced anxiety and memory impairments prior to stress exposure.
