Funding Information:
Our analyses are based on the assumption that all incident RA cases in the region are included in the EAC. This assumption is supported by the fact that the LUMC is the only referral centre in the region. Importantly, the referral region and strategy has not changed during the last two decennia; hence, if a proportion of patients with novel RA is not included in the cohort, this is presumably similar over time and does not affect our results on trends over time.
