PBM alleviates depression and anxiety like behaviors in mice: insight from local field potential.

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
backgroundDepression involves abnormal neural oscillations. Photobiomodulation (PBM) modulates such oscillations but lacks behavioral electrophysiological mechanistic studies. We explored PBM's effects on hippocampal CA1 oscillations and phase-amplitude coupling (PAC) in a depression model.
methodsMale C57BL/6J mice were randomly divided into saline, LPS (2 mg/kg i.p.), and LPS + PBM groups (n = 10/group for behavioral tests, n = 8/group for electrophysiology). LPS groups received lipopolysaccharide to induce neuroinflammation. The LPS + PBM group underwent 810 nm PBM (20 mW/cm², 12 min/day × 4 days) starting day 4 post-injection. Anxiety- and depression-like behaviors were assessed via open field, elevated plus-maze, and tail suspension tests. Wireless electrophysiology recorded CA1 local field potentials (LFP) during rest and behaviors. Oscillations and PAC were analyzed. Data are presented as mean ± SD; group differences were evaluated by one-way ANOVA with Bonferroni post-hoc correction and ɳ² effect sizes, with two-tailed p < 0.05 taken as statistically significant.
resultsPBM (20 mW/cm
conclusionPBM therapy ameliorates LPS-induced depression and anxiety behaviors while normalizing hippocampal CA1 oscillations and cross-frequency coupling. Its effects are state-dependent, modulating distinct frequency bands and PAC across rest and behavioral contexts, revealing potential electrophysiological therapeutic mechanisms.
