Ashwagandhaand Wake after sleep onset (WASO)
Only one source here so far, and it measured lower wake after sleep onset (WASO).
How sure anyone can be
Low certainty, level 2 of 4Further research is likely to change this.
The numbers reported
No number has been put on this yet. One source recorded only which way the numbers went — for now, that is all we have here.
One source, newest first
What we read is the published abstract, not the full paper, so a blank below may still be printed in the paper itself. A fixed rule worked this out from the source’s own fields. Nobody checked this rating by hand.
Randomised trial, 2020 · 144 participants
Low certainty, level 2 of 4A randomized, double blind, placebo controlled study to evaluate the effects of ashwagandha (Withania somnifera) extract on sleep quality in healthy adults.
Sleep Med. 2020;72:28-36. doi:10.1016/j.sleep.2020.03.012. PMID:32540634.

How this rating was reachedstarts at High, 2 steps down: risk of bias and imprecision
- Starts at High
- Risk of bias brought it down to Moderatethe abstract reports no risk-of-bias or quality appraisal, so study limitations cannot be ruled outNot in the abstract
- Imprecision brought it down to Lowthe abstract reports no confidence interval for the estimateNot in the abstract
- Ends at Low2 steps down.
- Checked, nothing to step it down for
- indirectness
- Inconsistency
- One study, so there was nothing to disagree
Imprecision stops at the first check that applies; others may apply too.
AI review could not confirm it — an AI agent re-read this finding against the saved source and at least one check failed. The batch record names the check and quotes the sentence that caused the doubt. No person read it.
What is still missing from these readings
- No number at all, only which way it went.
- One gives no likely range, so how precise that number is is unknown.
Something nobody wrote down is never a zero and never a guess.
Still to read for Ashwagandha
Four of the 18 things on our list for Ashwagandha have no reading here yet:
- Creatine Kinase (CK)
- DHEA-sulfate
- Free triiodothyronine (fT3)
- Heart rate variability (RMSSD)
Still to read means nobody here has got to it, not that it was tried and did nothing or that no research exists. A pairing on no list is not a gap: we never set out to read it.
