TABLE 1.
Index offense descriptive data on all subjects (N = 146), illustrating any differences between subjects with complete data and at least 5 years of follow-up (n = 100), and a column comprising subjects with incomplete data (n = 29) or less than 5 years of follow-up (n = 17).

Only subjects with complete data and at least 5 years of follow-up were included in the discrimination, calibration, and long-term risk prediction analyses. Data for item 1 was incomplete for some subjects, either because the subjects concerned were still undergoing forensic psychiatric care at the time of the study, or there were no release dates available. Naturally, this affects the total Static-99R score row of the table (missing item 1 scored as 0 for this comparison only).
