“Evaluation of a Multidisciplinary Pain Management Program in Reducing Opioid Use for Patients with Chronic Non-Cancer Pain: A Retrospective Study” (PubMed ID: 38112764) Note: The original title is in title case, I have converted it to sentence case for consistency. Also, the error code 504 does not seem to be directly related to the title of the research article, it is likely an error code for a server or network connection issue.
