CXCL9 and hip fracture: In men, adding CXCL9 as a continuous variable to a model, which already contained age at blood draw, dialect group, BMI, smoking, and history of diabetes, further increased the AUC (95% CI) from 0.65 (0.55, 0.76) in Model 2 to 0.74 (0.65, 0.83) in Model 3 for the prediction of hip fracture.
