Construction of nomograms based on MRI cartilage parameters for predicting the progression of OA. The distribution and total point number of predictive variables overlap along the nomogram scales. The box plot shows the categorical variables (e.g., KL grade ), with the box size indicating percentage. The density plot shows the distribution of continuous variables (e.g., WOMKP, MCMJSW, WOMADL, score0, scoreΔ12, scoreΔ24 and total score). The definite value of each red point corresponds to the scale of the variable’s axis (β(χ-m) term). The observation values overlap at the total score axis. A straight line is drawn through this point and downward extending to the risk axis, and the point of intersection with the risk axis represents the occurrence probability of the progression of KOA.
