  • Statistically significant (standardised difference >0.1) results are bolded.

  • Regional density of rheumatologists: 1 rheumatologist per 75 000 population—optimal; <1 rheumatologist per 75 000 population—suboptimal.

  • Remote distance to rheumatologist: ≥100 km between patient’s residence and nearest rheumatologist.

  • ADG, Aggregated Diagnosis Group; CVD, cardiovascular disease; IBD, inflammatory bowel disease.
