The effects of chronic sleep restriction on the hypothalamic-pituitary-adrenal axis and its interaction with abstinence from opioid use.
Article in Sleep, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
STUDY
objectivesThe hypothalamic-pituitary-adrenal (HPA) axis is critical in regulating responses to physiological and psychological disturbances. Chronic sleep restriction (SR) interacts with the HPA axis in ways that are poorly delineated. The present study evaluated how chronic SR alters pituitary and adrenal function. Chronic SR was studied both alone and in a model of opioid use disorder as a potential cause of HPA axis abnormalities during abstinence.
methodsAfter established self-administration of oxycodone or a saline control, male and female rats were either chronically sleep-restricted or allowed to sleep ad libitum for five weeks to permit changes in phenotype to manifest. Tests of pituitary and adrenal function were then carried out using acute CRH and dexamethasone-ACTH stimulation testing.
resultsSexual dimorphisms were prominent in the effects of chronic SR on the HPA axis which did not vary by prior opioid exposure. There were essentially no abnormalities in the HPA axis that were due to prior opioid exposure alone. In male SR rats, basal corticosterone concentrations decreased, ACTH responses to stimulation were enhanced, and ACTH suppression by dexamethasone was reduced. In female SR rats, the corticosterone response to CRH-stimulated ACTH release peaked early. Both male and female SR rats consumed more food relative to body weight than comparison rats, indicating homeostatic disruption that is known to require HPA axis mediation.
conclusionsChronic SR interferes with HPA axis dynamics in sexually dimorphic ways that are expected to differentially affect SR-induced pathophysiology and disease risks. Chronic SR caused the HPA axis abnormalities observed during abstinence, providing a biological linkage between two hypothesized risk factors in vulnerability to drug taking and relapse that demonstrate sexual dimorphisms.
