Patients were grouped into localized and widespread pain groups based on the widespread pain index (WPI\u00a0\u2265\u00a04). Clinical characteristics and levels of comorbidities were analyzed through physical examination and validated questionnaires. Differences between the groups and the power of pre\u2010treatment WPI in predicting pre\u2010treatment comorbidities and post\u2010treatment pain level improvement were statistically analyzed.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Patients with widespread pain showed higher somatization and anxiety levels.
