Figure 2. Estimates of Age-Adjusted All-Cause Mortality in 157 Men With No or Minimal Comorbidity.

All data are stratified by the occurrence of the observation of: A, prostate-specific antigen (PSA) failure (age-adjusted Cox P = .01); B, PSA of a nadir greater than 0.5 ng/mL (age-adjusted Cox P < .001); C, PSA doubling time less than 9 months (age-adjusted Cox P < .001); D, interval to PSA failure less than 30 months (age-adjusted Cox P = .002).
