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

introductionAccurate assessment of heat strain at initial stay time (IST; core temperature 38.0°C or Δ1.0°C above resting), when heat mitigation decisions are required, is critical for managing occupational heat exposure. We evaluated the relationship and agreement between physiological (Physiological Strain Index [PSI] and adaptive PSI [aPSI]) and perceptual (Perceptual Strain Index [PeSI]) indices during simulated occupational work performed until IST.

methodsNinety-seven healthy adults completed treadmill walking to IST at either moderate-intensity (200 W·m

resultsPeSI increased with PSI and aPSI during moderate- and heavy-intensity work (all p < 0.01). These relationships were not modified by group, environmental condition, body surface area, or aerobic fitness. However, agreement between perceptual and physiological indices was limited, showing wide limits of agreement between PSI and PeSI during moderate- (-2.3 to 4.2 AU) and heavy-intensity (-3.0 to 4.0 AU) work. The agreement between PeSI and aPSI was modestly improved but remained variable.

conclusionWe show that although perceptual responses increase with physiological heat strain, they do not reliably reflect physiological burden at IST, when decisions regarding the implementation of heat mitigation strategies are required.
