  1. aData not available for European sample; therefore, percentages calculated based on US sample only (concept elicitation: nĀ =ā€‰15, cognitive debriefing: nĀ =ā€‰19)
  2. bSelf-rated assessment of endometriosis-associated pain at its worst in the last 24ā€‰h (using a 0ā€“10 NRS where 0ā€‰=ā€‰no pain and 10ā€‰=ā€‰pain as bad as you can imagine). Classifications of pain based on Serlin et al. (1995) [40]
  3. cCounts not mutually exclusive
  4. dOf note: Two patients from the US sample had NRS scores < 3
