A specific bacteria that produces nitrite is linked to lower blood pressure.
Scientific Claim
There is a negative correlation between Corynebacterium durum and diastolic blood pressure (r = -0.44, P < 0.05), suggesting a potential protective role for this nitrite-producing bacterium in blood pressure regulation.
Original Statement
“Another interesting result was the positive correlation of Tannerella forsythia in tongue coating with systolic and diastolic blood pressure (r = 0.42 and 0.50, respectively, both P < 0.05), while the known nitrite-producing Corynebacterium durum correlated negatively with diastolic blood pressure (r = -0.44, P < 0.05) (Supplementary Table 2).”
Evidence Quality Assessment

appropriately stated
Study Design Support
Design supports claim
Appropriate Language Strength
association
Can only show association/correlation
Assessment Explanation
The study design is observational and shows correlation between Corynebacterium durum and blood pressure. The language 'correlated negatively' appropriately reflects the correlational nature of the findings.
