The paper describes the use of frequentist and Bayesian shared-parameter joint models of longitudinal measurements
of prostate specific antigen (PSA) and the risk of prostate cancer (PCa). The motivating dataset corresponds to the
screening arm of the Spanish branch of the European Randomized Screening for Prostate Cancer (ERSPC) study. The
results show that PSA is highly associated with the risk of being diagnosed with PCa and that there is an age-varying
effect of PSA on PCa risk. Both the frequentist and Bayesian paradigms produced very close parameter estimates
and subsequent 95% confidence and credibility intervals. Dynamic estimations of disease-free probabilities obtained
using Bayesian inference highlight the potential of joint models to guide personalized risk-based screening strategies.
