Exercise Duration Modulates Cortisol Release and Chronic Cortisol Exposure Jeopardises T Cell Effector Functions.
Article in Immunology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
Psychological stress has been linked to increased incidence and mortality of cancer. During stress, cortisol is released into circulation and regulates cellular processes including immune activity by acting on glucocorticoid receptors (GCRs) expressed by target cells. Chronic stress-induced cortisol has been suggested to promote tumour progression and compromise the efficacy of cancer treatments. Conversely, cortisol is also transiently secreted during exercise. Although exercise has been suggested to have beneficial effects against cancer, the impact of exercise-elevated cortisol on immune cell functions remains poorly understood. Here we studied the dynamics of cortisol secretion following exercise and how cortisol affects effector functions of T cells in the context of acute versus chronic stress. We show that 40 min of acute, high-intensity exercise in healthy adults significantly increased stable circulating cortisol levels whereas a 5-min sprint failed to. Acute exposure to cortisol for 4 h showed no negative effects on the proliferation, cytokine release, or killing activity of human CD3
