About Nomograms

The predictive tools that are offered on this site are called nomograms. They provide individualized predictions based on the characteristics of one single patient. Nonetheless, the predictions are derived from hundreds or even thousands of patients who presented with the same condition. Individualized predictions represent one of the advantages of the nomograms, relative to risk groupings of patient populations who share similar disease characteristics. Risk groupings provide average predictions, which may or may not apply to the patient interested in knowing his or her individual risk. Moreover, the nomograms provide the risk estimation on a 0-100% scale, which is substantially easier to understand and operationalize than for example a 6-fold increase in risk, which is the standard format of risk quantification in other prediction models.

All nomograms have been developed and validated in large patient populations and are highly generalizable. The tools provide the most objective, evidence-based, individualized risk estimation. They are meant to empower patients and to allow them to better understand their disease. Simultaneously, the nomograms are meant to assist physicians with difficult clinical decision-making and to provide consistent, standardized and reliable predictions. Comparisons between nomogram-derived predictions and those of expert physicians have repeatedly and convincingly confirmed the superiority of nomogram-based risk estimation.

Who can use nomograms?

Nomograms are designed for use by patients or physicians. For example, men who are at risk of Prostate Cancer as well as those diagnosed with the disease could use our prostate cancer nomograms. Patients at risk of bladder cancer or those already diagnosed with various stages of bladder cancer could use our bladder cancer nomograms. Patients with kidney cancer could use the kidney cancer nomograms. Finally, renal transplantation nomograms can be used to assess the functionality of transplanted kidneys. The nomograms are not only meant for patient use. Their primary role previously consisted of assisting physicians with clinical decision making.
