Sleep and cardiovascular effects of behavioural therapies for insomnia
Bibliographic record
Abstract
Background: Insomnia increases the risk for cardiovascular diseases. Stimulus control therapy (SCT) and sleep restriction therapy (SRT) are behavioural interventions which are effective for managing insomnia, but their effectiveness in alleviating symptoms precursor to or indicative of cardiovascular diseases is unknown. Aims: To evaluate the effects of SCT and SRT, on insomnia and cardiovascular symptoms, in persons with chronic insomnia. Methods: A randomised controlled trial was used. Participants (n=55) randomised to either SCT, SRT or no treatment group completed the study. Outcome data were collected before and after a 4-week treatment period. Results: Participants in the SRT group reported a reduction in perceived insomnia, and those in the SRT and SCT groups showed a reduction in cardiovascular symptoms. Conclusion: SRT and SCT are effective for improving insomnia and have the potential to reduce risk of cardiovascular diseases in individuals with chronic insomnia, as well as to manage insomnia when it is experienced with cardiovascular diseases.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
