Two specific types of oral bacteria (Neisseria flavescens and Haemophilus parainfluenzae) are linked to better insulin sensitivity and lower blood pressure in people without diabetes.
Scientific Claim
Higher relative abundance of Neisseria flavescens and Haemophilus parainfluenzae is associated with lower insulin resistance and systolic blood pressure in adults without diabetes.
Original Statement
“Higher relative abundance of Neisseria flavescens and Haemophilus parainfluenzae were associated with lower insulin resistance and mean SBP, and lower plasma glucose, SBP, and DBP, respectively.”
Evidence Quality Assessment
Claim Status
appropriately stated
Study Design Support
Design supports claim
Appropriate Language Strength
association
Can only show association/correlation
Assessment Explanation
The study is observational and cross-sectional, so 'associated with' is the correct verb strength. The claim accurately reflects the statistical relationship without implying causation.
