  1. ICD-10 = International Classification of Diseases
  2. OR = Odds ratio (adjusted by sex, age, company size and field of industry), CI = Confidence interval
  3. 1.0 = reference group (non-FA = non-frequent attenders, patients that were never in the top decile were considered as a reference group)
  4. FA status was defined as the top decile of attenders (frequent attender 10%, FA10),
  5. 1-year-FA = Patients that were in the top decile of attenders in one of the study years (2014, 2015 or 2016)
  6. 2-year-FA = Patients that were in the top decile in any two study years (2014, 2015 or 2016)
  7. pFA = Patients that were in the top decile in all three study years (2014, 2015 and 2016)
