If I were a betting man (and I am) then I think this will show a slight result under LP, thereby justifying why the trial wasn't unethical, but less than GET/CBT. Simultaneously defends against the accusation that testing a quack treatment on children is misconduct, but doesn't lead to the promotion of outright quackery* that might have people like Sense About Science getting worried.

*the promotion of GET is quackery given that it has been shown to fail on all objective measures, but it at least has the veneer of science unless one digs into the trial design. Whereas even on the surface, LP screams 'woo' on first contact. I can't see even the SMC standing up and promoting something that has been heavily criticised by the wider skeptic community.
