Interlocks for first offenders: effective?
The study provides evidence that interlocks are as effective with first offenders (approximately 60% reduction in recidivism when on the vehicle) as they are for multiple offenders. In addition, the benefits of requiring an interlock for first offenders exceed the costs by a factor of three.
In our study, lateral pelvic recurrence was a major cause of locoregional recurrence, and ypN+ and lateral lymph node size were risk factors for lateral pelvic recurrence.
