Chronic low back pain (41.4%) and fibromyalgia (21.1%) were most prevalent. Women and individuals aged 31 to 50 years had the highest COPC prevalence. Many COPC pairs co\u2010occurred more frequently than expected by chance (eg, fibromyalgia and chronic low back pain: observed\/expected ratio 1.35; migraine and chronic low back pain: observed\/expected ratio 1.42). Strongly associated dyads included urologic chronic pelvic pain and vulvodynia (OR 10.46).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>A substantial burden and distinct multimorbidity patterns of COPCs exist among patients with ARDs, suggesting shared pathophysiologic mechanisms.
