Oral respiration modulates sensory and cognitive brain potentials differently than nasal respiration.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Respiration influences brain activity and awareness through two mechanisms: direct rhythmic entrainment via olfactory bulb (OB) stimulation and indirect modulation through baroreceptor (BR) activity fluctuations that affect cortical excitability. During nasal breathing, both mechanisms are active and can influence sensory event-related potentials (ERPs). To isolate the contribution of BR activity, we tested the same paradigm during oral breathing, which eliminates OB stimulation. Results showed that sensory ERPs varied with the cardiac (with delayed timing) but not with the respiratory phase. The P3a component was modulated by awareness only when BR activity was low (during inhalation and diastole), while the visual awareness negativity (VAN) and P3b were modulated by awareness across all conditions. These findings indicate that BR fluctuations alone cannot fully account for the respiratory modulation of awareness-related ERPs, but they require entrainment of brain activity modulated by mechanical OB stimulation.
