Distinct subtypes of knee osteoarthritis: data from the Osteoarthritis Initiative.

Rheumatology (Oxford, England) - 1 Sept 2015

Waarsing Jan H, Bierma-Zeinstra Sita M A, Weinans Harrie

Abstract excerpt

OBJECTIVE: OA is suspected to be a collection of distinct subtypes, each with different aetiology and clinical characteristics. We aimed to explore the existence of different subtypes of knee OA, using cluster analysis of the data of the OA Initiative. METHODS: We used latent class cluster analysis (LCA) to cluster baseline data of 518 subjects of the OA Initiative progression cohort. Data included radiographic...
