Table IV A the best unconditional logistic regression model adjusted for known prostate cancer risk factors is presented based on −2 log likelihood scores. Income, 5 alpha-reductase inhibitor use, and city of recruitment failed to reach statistical significance in the analyses and did not improve −2 log likelihood scores and were excluded.
