  1. CI: Confidence Interval; BMI: Body Mass Index; MSA: Metropolitan Statistical Area
  2. a Survey weighting, stratification, and clustering accounted for reflecting unbiased, national annual estimates of visit occurrences for the portion of the population meeting the study inclusion and exclusion criteria
  3. b Out of the 1,659 survey visits as which fibromyalgia was diagnosed, IBS (n = 17; Relative Standard Error [RSE] = 32%) and lupus (n = 25; RSE = 35%) and general anxiety disorder (RSE = 35%) were either reported at less than 30 visits and/or had a RSE > 30%. Per the NCHS, the estimate for these variables in this table are potentially unreliable due to the small count (and/or elevated RSE value). Caution is urged in interpreting this estimate
  4. c Out of the 1,659 survey visits as which fibromyalgia was diagnosed, sleep disorder, cognitive function symptoms, cramps/spasms, weight gain, stomach pain, nausea, diarrhea and itching was reported at less than 15 visits. Per the NCHS, these estimates are entirely unreliable and thus not reported in this table even though the variables were included in the model
