Abstract excerpt

OBJECTIVE: This study aimed to identify distinct clinical phenotypes within a Chinese cohort of patients with psoriatic arthritis (PsA). METHODS: A total of 1074 patient data were analyzed from the Chinese Psoriatic Arthritis Registry (CREPAR). A two-step clustering approach was used to identify patient subtypes based on the unsupervised clustering of baseline clinical characteristics. Kaplan-Meier curves were...
