9- Test statistics were t values for changes of offences and were chi-square values for any recidivism between pre and post period
10-Odds ratios for any recidivism between pre and post-period was estimated using McNemar's test
11- P value for difference in any recidivism between pre and post-period for DTCV Cohort
12- P value for difference in any recidivism between pre and post-period for matched comparison group
13- Odds ratios for CDSA related recidivism between pre and post-period was estimated using McNemar's test
14- P value for difference in CDSA-related recidivism between pre and post-period for DTCV cohort
15-P value for difference in CDSA-related recidivism between pre and post-period for matched comparison group
