The Claim
The overall metabolomic signature of physical activity, based on 24 metabolites including phosphatidylcholines and lysophosphatidylcholines, does not significantly mediate the association between physical activity and colorectal cancer risk, with a natural indirect effect of 0.994 (P = 0.21).
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
A specific set of 24 metabolic markers related to physical activity does not explain the observed link between physical activity and colorectal cancer risk, as the statistical mediation effect is not significant.
See the scientific wording
The overall metabolomic signature of physical activity, derived from 24 metabolites including phosphatidylcholines and lysophosphatidylcholines, does not significantly mediate the association between physical activity and colorectal cancer risk, with a natural indirect effect of 0.994 (P = 0.21).
What the research says
1 studyStudy: Identifying Metabolomic Mediators of the Physical Activity and Colorectal Cancer Relationship
The study found that while one specific chemical in the body links physical activity to lower colon cancer risk, the whole group of 24 chemicals together doesn’t explain the connection — which matches the claim.
