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 health risks associated with acute noise exposure are increasing, particularly the risk of mental health. This study aims to identify the association between acute high-intensity noise exposure and anxiety behavior in male rats, and to explore the associated neurobiological mechanisms. Male rats were subjected to different levels of acute high-intensity noise to determine the intensity that causes long-lasting anxiety-like behaviors. Anxiety-like behaviors were evaluated using the open field test (OFT) and the elevated plus maze test (EPMT) on the third day and 1month post-exposure, respectively. A range of techniques, including immunofluorescence staining, western blot, ELISA, and real-time quantitative PCR, were used to investigate neuronal apoptosis, glial cell activation, neuroinflammation, and blood-brain barrier (BBB) disruption in the hippocampus. Upon exposure to 135 dB of acute noise, male rats exhibited enduring anxiety-like behaviors. Subsequent investigations discovered that this noise intensity not only activated glial cells and triggered neuroinflammation within the hippocampus but also decreased the expression levels of ZO-1, claudin-5, and occludin, suggesting a disruption of the BBB. Additionally, this exposure was associated with the induction of neuronal apoptosis in the hippocampal region. In conclusion, acute exposure to 135 dB noise may cause persistent anxiety in male rats through a cyclical interaction between neuroinflammation and BBB disruption, potentially leading to neuronal apoptosis.
