Following on from PharmD_Rodriguez — and this may be the naive question:

Was that from a primary source or from a summary of one?

If you are comparing against somebody else’s result, check that you are comparing the same measurement taken the same way.

Worth saying that the confident version of this is more useful to the person writing it than to the person reading it.

Moderator note: reminder that nothing in this thread is medical advice, and that clinical claims need a source. No action needed from anybody.

Saving this. It is the first explanation that did not require me to already understand it. Adding it to my notes with a link back to this thread.

Adding the clinical framing, because it changes how the question reads. There is a difference between no evidence and evidence of no effect, and this subject is one where the two get swapped freely in both directions.
