Why the study?
Opioid dependence management requires dose titration based on withdrawal symptoms, but clinical assessment poses challenges with subjective reporting.
Does heart rate variability correlate with subjective opioid withdrawal in patients with opioid dependence?
Population
Adult males across three groups (inpatient detoxification, stabilized on buprenorphine, and healthy controls)
Comparison
Inpatient detoxification vs buprenorphine-stabilized substitution treatment vs healthy controls
Design
Exploratory study

Does heart rate variability correlate with subjective opioid withdrawal in patients with opioid dependence?
Heart rate variability parameters are not robustly associated with subjective opioid withdrawal, suggesting limited utility as an objective marker for withdrawal assessment.
