Characterization of a large cohort of Colombian spondylarthritis patients: a cohort that must be considered for actual classification criteria. Supplementary material

Abstract

Background: Spondyloarthritis (SpA) can be classified by clinical presentation using Assessment of SpondyloArthritis international Society (ASAS) criteria. Though useful in many cohorts, their usefulness in Colombia needs to be clarified. The study aimed to describe a large Colombian group of SpA patients, evaluate ASAS criteria's sensitivity in the GESPA cohort, and propose axSpA criteria modification.
