Nomograms are graphical representations of equations that predict medical outcomes. Nomograms use a points-based system, whereby a patient accumulates points based on the levels of his or her risk factors. The cumulative points total is associated with a prediction, such as the predicted probability of treatment failure in the future. Nomograms are attractive as medical prediction tools, because they can consider multiple variables simultaneously to find the best prediction for an individual patient. Nomograms have demonstrated better accuracy than both risk-grouping systems and physician judgment. This improved accuracy should translate into more appropriate patient counseling and medical decision making.
