Cowen et al. [94]	2006	Probability nomogram development	Life expectancy (5–15 years)	506	Age, Charlson comorbidity index, presence of angina, systolic blood pressure, body mass index, smoking, marital status, PSA< Gleason sum, clinical stage, treatment type (radical prostatectomy vs radiotherapy vs other)	73%	Internal
