In pregnant women, higher levels of Veillonella parvula bacteria in the mouth were linked to lower diastolic blood pressure, and showed a similar but less strong pattern for systolic blood pressure.
Scientific Claim
The abundance of Veillonella parvula specifically showed a negative correlation with maternal diastolic blood pressure (rho = -0.47, p = 0.02) and a trend toward negative correlation with systolic blood pressure (rho = -0.39, p = 0.06) in pregnant women.
Original Statement
“The abundance of V. parvula correlated negatively with maternal diastolic blood pressure (rho = −0.47, p = 0.02) and trended toward a significant correlation with systolic blood pressure (rho = −0.39, p = 0.06) (Figure 4C,D).”
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 claim correctly states 'correlated negatively' and 'trended toward a significant correlation' which accurately reflects the statistical findings without implying causation.
