From: Widespread pain in axial spondyloarthritis: clinical importance and gender differences
Graphical illustration of the contribution of each Bath Ankylosing Spondylitis Disease Activity Index item and spinal, articular and non-articular pain sum scores to peripheral and axial disease activity factors* in men and women with axial spondyloarthritis (n = 170). BASDAI, Bath Ankylosing Spondylitis Disease Activity Index; (non)-articular and spinal pain sum of pain area estimates were based on body charts (0–100%). * PCA with varimax rotation in the total group (a), men (b) and women (c). Rescaled rotated factor loadings are presented. Level of statistical significance was set at p < .05. Lines connect items to the construct they represent. Solid or dashed lines represent larger (> .60) or smaller (< .60) contributions to the underlying construct, respectively
