Detailed results of both paradigms separately were published elsewhere. The main goal of the current report is to describe the relationship between the responses to these two paradigms measuring distortions in symptom perception in a well-described sample of patients with fibromyalgia and\/or chronic fatigue syndrome.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Methods<\/jats:title>\n            <jats:p>Patients (<jats:italic toggle=\"yes\">N<\/jats:italic> = 81) with fibromyalgia and\/or chronic fatigue syndrome participated in a test session comprising four well-validated paradigms, including the picture-viewing and rebreathing paradigm.
