People with severe calcium buildup in their heart arteries tend to have less of a specific bacteria called Fusobacterium nucleatum in their blood than people with healthy arteries.
Evidence Quality Assessment

Appropriate Language Strength
association

Assessment Explanation
The claim uses precise statistical values (p = 0.0012, FDR = 4.8%) and clearly compares two groups, indicating a correlational finding from observational data. It avoids implying causation, which is appropriate since no intervention was applied. The use of 'significantly less frequent' is statistically sound and correctly reflects association, not causation.
More Accurate Statement
“The presence of Fusobacterium nucleatum in peripheral blood is significantly associated with lower levels in individuals with coronary artery calcification (CAC > 500) compared to those with no calcification (p = 0.0012, FDR = 4.8%).”

Gold Standard Evidence Needed
According to GRADE and EBM methodology, here is what ideal scientific evidence would look like to definitively prove or disprove this specific claim, ordered from strongest to weakest evidence.
Evidence from Studies
Supporting (1)
Presence of periodontal pathogenic bacteria in blood of patients with coronary artery disease
The study found that a specific mouth bacteria called Fusobacterium nucleatum is much less common in the blood of people with severe artery calcification than in healthy people — which is exactly what the claim says.
