I don't have a science degree but I know enough to know that being slightly better than a placebo is not a good result.

There are many ways to get a small improvement in AHI. To get a significant improvement you need a CPAP. This study shows there is a small improvement to most people, but not a significant one.

Below may be some helpful information to look at.

Degrees of severity of sleep apnoea

The severity of sleep apnoea depends on how often your breathing is interrupted. As a guide:

• normal sleep – fewer than 5 interruptions per hour
• mild sleep apnoea – between 5 and 15 interruptions per hour
• moderate sleep apnoea – between 15 and 30 interruptions per hour
• severe sleep apnoea – more than 30 interruptions per hour.
