Nomogram predicting responders to mononuclear cell transplantation for no-option critical limb ischemia. Each variable is given a score by projecting its status to the upper point of the scale (0–100) with a straight line. Based on a total score calculated by summing the whole scores of the 5 variables, the predicted probability can be determined by projecting the total score line straight to the probability scale line at the bottom. Log, Base-10 logarithm; TcPO2, transcutaneous pressure of oxygen; CD, cluster of differentiation
