Cholesterol and blood fats
Red Yeast Riceand LDL cholesterol
All three sources here measured lower LDL cholesterol.
How sure anyone can be
Moderate certainty, level 3 of 4Further research may change this.
The most certain of the three findings here; each record carries its own.
The numbers reported
One source’s range, drawn against its own line of no difference and scaled to its own numbers.
-1.03-0.87 mmol/L-0.71
This range stays on one side of the no-difference line.
Three sources, 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 person went through the criteria and recorded which brought the rating down. Their reasons are not on record here.

What is still missing from these readings
- One gives no likely range, so how precise that number is is unknown.
- One do not say how many people took part.
- Amount taken — Not in the abstract.
- For how long — Not in the abstract.
Something nobody wrote down is never a zero and never a guess.
Red Yeast Rice is not on our to-read list
Red Yeast Rice is not on our to-read list, so nothing here is set out to read next for it.
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.
