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

Why mammals defend species-specific body temperatures, often across a range extending from the low 30s to around 40 °C, remains a central question in comparative physiology. In this Commentary, it is suggested that mammalian heat tolerance is best understood not through single environmental thresholds or global mean temperature, but through the interaction of microclimate, heat-balance physics, effector coordination and cardiovascular constraint. Using humans as one focal example within a broader comparative framework, it distinguishes endothermy from homeothermy and then consideration as to how different mammalian lineages solve the problem of heat balance through differing combinations of evaporative cooling, behavioural refuge, water conservation, heterothermy and tolerance of transient body temperature elevation. The discussion then addresses mechanistic pathways of heat exchange, emphasising the importance of radiation, airflow and evaporative opportunity within the immediate microclimate, and present a microclimate-linked Arrhenius/Q
