Acute Whole-Body Heat Exposure Modulates EEG Microstate Dynamics, Phase-Lagged Connectivity, and Cortical Source Activity.

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
Acute exposure to elevated ambient temperature affects physiological regulation, thermal perception, and cognitive functioning, yet its influence on the spatiotemporal organization of human brain activity remains insufficiently understood. This study investigated temperature-related changes in EEG spectral power, microstates, functional connectivity, and cortical source activity. Fifteen healthy male participants completed three randomized 45-min seated exposures at ambient temperatures of 21, 30, and 38 °C while wearing standardized winter protective clothing (3.2 clo). EEG, skin temperature, core body temperature, and subjective thermal sensation were recorded. Mean skin temperature, core body temperature, and thermal-sensation votes increased with temperature and exposure duration. Global delta-band connectivity differed significantly across temperatures (χ
