The Claim
There is suspicion of publication bias in the meta-analysis of serum/plasma polyols and cardiovascular events, indicating that smaller studies showing no or negative associations may be underrepresented in the published literature.
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.
Some researchers think that studies showing no link between sugar-related compounds in blood and heart problems might be missing from the research — especially smaller ones — which could skew what we think is true.

What the research says
1 studyStudy: Artificial Sweeteners and Cardiovascular Disease: Systematic Review and Meta-analysis.
The study looked at sugar substitutes in blood and heart problems, and said the results might be skewed because smaller studies with negative results could be missing. This matches the claim.
