Both axSpA and PsA patients with LDA had pain scores ranging from 14.0 to 21.4\/100 and fatigue scores ranging from 3.1 to 3.6\/10. Substantial burden in physical disability and mental well-being were observed, with low physical and mental component summary scores on the 36-item Short Form Health Survey. AxSpa patients in BASDAI LDA had higher ESR and lower disability than those in ASDAS-ESR LDA. cDAPSA classified nearly twice as many PsA patients into LDA than MDA.
