Abstract. Nolan RP, Floras JS, Ahmed L, Harvey PJ, Hiscock N, Hendrickx H, Talbot D (University Health Network and University of Toronto; Women’s College Hospital, University of Toronto, Toronto, ON, Canada; and Unilever Discover, Colworth Science Park, Sharnbrook, UK). Behavioural modification of the cholinergic anti‐inflammatory response to C‐reactive protein in patients with hypertension. J Intern Med 2012; 272 : 161–169. Objectives. A central hypothesis of the cholinergic anti‐inflammatory reflex model is that innate immune activity is inhibited by the efferent vagus. We evaluated whether changes in markers of tonic or reflex vagal heart rate modulation following behavioural intervention were associated inversely with changes in high‐sensitivity C‐reactive protein (hsCRP) or interleukin‐6 (IL‐6). Design. Subjects diagnosed with hypertension ( n = 45, age 35–64 years, 53% women) were randomized to an 8‐week protocol of behavioural neurocardiac training (with heart rate variability biofeedback) or autogenic relaxation. Assessments before and after intervention included pro‐inflammatory factors (hsCRP, IL‐6), markers of vagal heart rate modulation [RR high‐frequency (HF) power within 0.15–0.40 Hz, baroreflex sensitivity and RR interval], conventional measures of lipoprotein cholesterol and 24‐h ambulatory systolic and diastolic blood pressure. Results. Changes in hsCRP and IL‐6 were not associated with changes in lipoprotein cholesterol or blood pressure. After adjusting for anti‐inflammatory drugs and confounding factors, changes in hsCRP related inversely to changes in HF power (β =−0.25±0.1, P = 0.02), baroreflex sensitivity (β = −0.33±0.7, P = 0.04) and RR interval (β = −0.001 ± 0.0004, P = 0.02). Statistically significant relationships were not observed for IL‐6. Conclusions. Changes in hsCRP were consistent with the inhibitory effect of increased vagal efferent activity on pro‐inflammatory factors predicted by the cholinergic anti‐inflammatory reflex model. Clinical trials for patients with cardiovascular dysfunction are warranted to assess whether behavioural interventions can contribute independently to the chronic regulation of inflammatory activity and to improved clinical outcomes.

Not 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.
