I hope you are right. But your other comments may underestimate the complexity of the interpretation. What if (and I am just making these up) the apnea episodes are reduced by 50% during just the first five hours? By 25%? For three hours? What if there are changes in sleep architecture associated with 'successful' apneic reduction? Does the latter outweigh the former in clinical benefit? This is where you could end up with differences in opinion even amongst SA experts.
Again, I am just trying to depict what questions could arise. Why it would take so long to answer them--I have no idea. I like your hypothesis, but I am not yet ready to surrender my wariness.
