Association between cortical DXR-porosity and current distal radius fracture.

Association between cortical DXR-porosity and current distal radius fracture tested in unadjusted and adjusted logistic regression models. aAdjusted for age. bInflammatory or endocrine disease (fracture group vs. control group): other rheumatic diseases than rheumatoid arthritis (2 vs. 2); asthma/chronic obstructive lung disease asthma (10 vs. 9); diabetes mellitus (4 vs. 8); hyperparathyroidism (1 vs. 1); hypothyroidism (5 vs. 9); kidney disease (1 vs. 0). cExercise more than 30 minutes three times a week. dCalcium/vitamin D (29 vs.17); bisphosphonates, selective oestrogen receptor modulator, or oestrogen (22 vs.16). eDue to collinearity between the DXR measures porosity, BMD, CT and W these variables are not in the presented multivariable analysis. DXR: digital X-ray radiogrammetry; BMI: body mass index; RA: rheumatoid arthritis; GC: glucocorticoid; DXA: dual energy X-ray absorptiometry; BMD: bone mineral density; CT: cortical thickness; W: bone width.
