                                        g  For the first 4 yr of the study, PSA DT <2y was used as a trigger. This criterion identified 10% of patients as high-risk and was considered overly stringent. In 1999 the cut-off
                                        was increased to 3 yr. From 1995 to 2002 PSA DT was calculated by a statistician using linear regression of all PSA values after the patient left the clinic and the 95% upper bound
                                        confidence limit of PSA DT had to be <3 yr. Later PSA DT was calculated by physicians who used PSA fluctuations to determine whether PSA DT was “truly” <3 yr.
                                        h  The model generates 2 reclassification curves (high and low risk) which, when overlaid over PSA data of each patient, defines 3 risk zones of high, intermediate and low risk of
                                        reclassification. A patient with a PSA consistently in the high risk zone is recommended to undergo treatment.
