Fig. 2From: Hyaline cartilage calcification of the first metatarsophalangeal joint is associated with osteoarthritis but independent of age and BMIStructural equation model. Manifest (measured) variables are represented by boxes, latent (i. e. not observable) variables are represented by circles. Abbreviations: hOA = histological osteoarthritis grade, CC = cartilage calcification, Age = age in years, BMI = body mass index [kg/m2], CCL/R = DCR-detctable hyaline cartilage calcification of the left/right central axial slab of MH, OAL/R = histological OA grade (by OARSI) of the left/right MHBack to article page
