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
Biological thermoreception extends beyond mere temperature detection, capturing nuanced cues such as sunlight, wind chill, humidity, and object contact. However, artificial thermoreceptors rarely match the acuity and perceptual richness with their biological counterpart, leaving a critical gap in thermosensory functionality for human-machine integration. Here, we introduce a structurally programmed iontronic platform that leverages energy landscape engineering in a heterogeneous polymer electrolyte to establish a continuous distribution of potential wells hosting a continuum of ionic carrier states. This architecture enables semiconductor-like thermally activated conduction by ionic carriers, achieving detection of temperature variations as small as 8 mK. Building on this platform, we develop a biomimetic ionic skin that interprets airflow, humidity, solar irradiation, thermal conductivity variations, and evaporative cooling through thermal cues, mirroring the multifaceted thermoreception of biological skin. This work complements the existing research paradigm of iontronics by integrating solid-state physics principles. The artificial thermoreceptor thus narrows the gap between artificial and biological thermosensation, advancing human-machine integration and biohybrid systems.
