Reading the Summary of findings

Two questions on what certainty means.

1. The Summary of findings says the effect on insomnia severity has moderate certainty. What does that mean?
The true effect is probably close to the estimate, but it may be substantially different
The true effect is certainly the estimate
There is no evidence of an effect
Moderate means half the trials found an effect
2. An edge is backed only by observational cohort studies. Where does Evidence's GRADE rating start it?
High
Moderate
Low
It isn't rated

Stuck?
