By the way the Janzens seem to think that just because a kid is wearing a brace, the brace did something. They are not running a controlled study so they can't say how successful the treatment is. This is why controls are needed.

The BrAIST study showed that about half the kids who didn't wear a brace were "successes" compared to 73% of the braced group. That means most of the "successes" in the braced group were not due to the brace. Then there were the bracing failures.

I think they calculated that they had to treat about 4 kids just to get one "success" from bracing.

Since some of the "successes" may have included kids with up to a 49* curve with up to 25% growth remaining, I think they should have also calculated the percent of kids who were "successes" at the end of the study but who will likely or almost certainly need surgery. That would be any kid with a >40* curve with no growth remaining or any kids with 35* curve or better with any growth remaining. Any kid with >30* curve at maturity is at risk of progressing to surgery in their life time.

The main elephant in the room is what is the Janzeneseses base for calculating success rate? There is no way they are that successful when even BrAIST was not. There is something very funny here.
