In pregnant women, higher levels of Veillonella bacteria in the mouth were linked to higher levels of Prevotella bacteria.

Scientific Claim

The abundance of Veillonella and Prevotella in the oral microbiota was positively correlated with each other in pregnant women (rho = 0.42, p = 0.02).

Original Statement

“The abundances of Veillonella and Prevotella were positively correlated (rho = 0.42, p = 0.02).”

appropriately stated

Study Design Support

Design supports claim

Appropriate Language Strength

association

Can only show association/correlation

Assessment Explanation

The claim correctly states 'positively correlated' which accurately describes the statistical relationship found in the observational study without implying causation.

Similar Assertions

In pregnant women, having more Veillonella bacteria in the mouth was linked to lower blood pressure readings.

In pregnant women, the amount of Prevotella bacteria in the mouth wasn't linked to blood pressure levels.

81%

Pregnant women who later got preeclampsia had less of a specific bacteria called Veillonella parvula in their mouths compared to women who stayed healthy during pregnancy.
