  1. 1 Total N = 156, 151 participants reported 1 or more conditions.
  2. 2 For most conditions, an example or two were provided to illustrate the diagnostic category. For example, 'other rheumatic disease" was presented as "rheumatic disease such as fibromyalgia or lupus"; and "nerve condition" was presented as "nerve condition such as Parkinson's disease or multiple sclerosis."
