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

Introduction: Infrasound (<20 Hz) was an inaudible mechanical vibration that threatened public health, especially the central nervous system (CNS) in air environments. In fact, infrasound was also produced by large ships or underwater apparatus, which had potential hazard to underwater operators or divers. However, the propagation characteristics of sound waves in air differed from that in water, and there was no experimental evidence on the potential bioeffects of underwater infrasound. In the present study, we systematically evaluated cerebral injury in Bama mini pigs induced by underwater infrasound. Methods: Forty-two Bama mini pigs (weighing 10-15 kg) were randomly divided into seven groups. After wearing a respiratory mask, the animals were submerged to a depth of 10 meters and exposed to infrasound at frequencies of 8 Hz (145.4 ± 0.2 dB re 1 μPa, 156.2 ± 1.0 dB re 1 μPa), 12 Hz (145.3 ± 0.2 dB re 1 μPa, 161.9 ± 2.4 dB re 1 μPa), and 20 Hz (145.5 ± 0.3 dB re 1 μPa, 165.9 ± 0.3 dB re 1 μPa). Then cerebral function was assessed using electroencephalography (EEG); morphological injuries were evaluated by HE staining, Nissl staining, and immunostaining; oxidative stress and inflammatory cytokines were detected via ELISA assays; and the underlying molecular mechanisms were explored through RNA sequencing and transcriptome analysis. Results and discussion: Compared with the control group, underwater infrasound at 8 Hz led to alterations in EEG in partial brain regions, but with no significant changes in the 12 Hz and 20 Hz groups. In contrast, underwater infrasound at 20 Hz and 12 Hz directly induced histological injury, decreased neuron density, and increased cell apoptosis immediately, but had no impact on histological and neuronal injury induced by 8 Hz exposure. Additionally, there was no significant influence on oxidative stress among all groups. Finally, transcriptome analysis revealed activation of immune and cell apoptosis pathways and key genes. These results provided direct evidence for the adverse effects of underwater infrasound on brains.
