AB Background: Spondyloarthritis, (axial (axSpA), peripheral (pSpA)) and psoriatic arthritis (PsA)) share enthesitis as a hallmark clinical feature. Reliable clinical instruments have been developed to assess enthesitis: Spondyloarthritis Research Consortium of Canada Enthesitis (SPARCC), Leeds Enthesitis Index (LEI), Maastricht Ankylosing Spondylitis Enthesitis Score (MASES) and MEI (Mander Enthesitis Index). Since these four indexes include different enthesis locations, they may capture a different number of patients with enthesitis in the different SpA entities PB Bmj publishing group SN 0003-4967 YR 2022 FD 2022-06-01 LK http://hdl.handle.net/10668/20059 UL http://hdl.handle.net/10668/20059 LA en DS RISalud RD Apr 8, 2025
