Purpose: To determine the probability of having prostate cancer (PCa) using the combination of serum level of prostate-specific antigen (PSA) and age.
Materials And Methods: A total of 160 patients and 190 controls were enrolled in this hospital-based case-control study. Using a logistic regression model and the odds ratio of age and PSA level, the probability of PCa was estimated based on serum level of PSA and age of the participants.
