A micro-to-macroscale and multi-method investigation of human sweating dynamics.
Article in Journal of the Royal Society, Interface, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Sweat secretion and evaporation from the skin dictate the human ability to thermoregulate and thermal comfort in hot environments and impact skin interactions with cosmetics, textiles and wearable electronics/sensors. However, sweating has mostly been investigated using macroscopic physiological methods, leaving micro-to-macroscale sweating dynamics unexplored. We explore these processes by using a coupled micro-imaging and transport measurement approach used in engineering studies of phase change processes. Specifically, we used a comprehensive set of 'macroscale' physiological measurements (ventilated capsule sweat rate (SR), galvanic skin conductance and dielectric epidermis hydration) complemented by three microscale imaging techniques (visible light, midwave infrared and optical coherence tomography imaging). Inspired by industrial jet cooling devices, we also explore an 'air jet' (versus cylindrical) capsule for measuring SR. To enable near-simultaneous application of these methods, we studied forehead sweating dynamics of six supine subjects undergoing passive heating, cooling and secondary heating. The relative dynamics of the physiological measurements agree with prior observations and can be explained using imaged microscale sweating dynamics. This comprehensive study provides new insights into the biophysical dynamics of sweating onset and following cyclic porewise, transition and filmwise sweating modes and highlights the roles of stratum corneum hydration, salt deposits and microscale hair.
