  1. Reference = Ref = participants without fibromyalgia and musculoskeletal pain disorders
  2. MTH = mean threshold of hearing based on pure tone audiometry at frequencies 0.5, 1, 2 and 4 kHz on both ears
  3. HADS-A = self-reported questionnaire for symptoms of anxiety
  4. HADS-D = self-reported questionnaire for symptoms of depression
  5. aDescriptive comparison of categorical variables performed with chi-square and continuous variables with two-sided t-test
