Well, that was the problem. The combination of the two produced a reduction. What they were unable to do, and what other studies have been unable to do, was separate those two pieces in the same study and say whether it was the electronic monitoring or the programming that resulted in the effect. What we have, though, is a lot of other research that clearly demonstrates that those treatment programs have a strong positive effect.
We know that, at a minimum, the programming had an effect. What we can't determine from the research that's been done is the incremental benefit of the electronic monitoring. That's the challenge.
