*Reflected by having a balanced specificity and sensitivity.1 

328 patients with axSpA and ≥1 ASDAS measurement in 2016–2022 were selected from a prospective multicentre Dutch registry (SpA-Net). Single patients could contribute multiple treatment intensification events, with only the first observation per patient per calendar year included in the analyses. Only anti-inflammatory drugs (NSAIDs, [b/cs/ts]DMARDs, corticosteroids) were considered with regards to treatment intensification and approximately two-thirds of patients (211/328 [64.3%]) were receiving b/tsDMARDs at some point during the study period.1
