1 · What the graph read from it

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.

2 · The registry

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 organisms are open thermodynamic systems in which internal structure and function arise from a network of heat- and entropy-producing processes, requiring external export of heat and entropy to the environment. System stability, including health and healing, is hypothesized to relate to the mass-normalized rate of entropy production and export, and the capacity to augment both when required. Using a novel methodological framework that allows the continuous measurement of heat fluxes and body temperature, we can estimate internal entropy production and external entropy export in humans during exercise under heat stress. We report the impairment of entropy export leading to entropy accumulation in association with increasing age, reduced fitness, and the presence of diabetes. In all conditions, impairment was also found to be negatively correlated with the VO
