In rats that are prone to high blood pressure, having more of a certain type of bacteria (Actinobacteria) in the mouth is linked to lower blood pressure.

Scientific Claim

Oral Actinobacteria abundance is inversely associated with blood pressure levels in rats with genetic predisposition to hypertension.

Original Statement

“Oral Actinobacteria were inversely associated with BP.”

From study:Beyond the Gastrointestinal Tract: Oral and Sex-Specific Skin Microbiota Are Associated with Hypertension in Rats with Genetic Disparities.

Appropriate Language Strength

association

Can only show association/correlation

Assessment Explanation

The study is observational and shows statistical association only. The phrase 'inversely associated' correctly reflects the correlational nature of the findings without implying causation.

Similar Assertions

In rats, a specific part of the genome (RNO10) controls the amount of Actinobacteria bacteria in the mouth, and this is linked to blood pressure levels.

82%

In rats prone to high blood pressure, the types and amounts of bacteria in the mouth are affected by the rat's genetic makeup.

78%

In rats with different genetic modifications that affect blood pressure, the types and amounts of bacteria in the mouth differ between these strains.
