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.
Scientific Claim
Women who later developed preeclampsia had significantly lower abundance of Veillonella parvula in their oral microbiota compared to normotensive pregnant women at 36 weeks gestation.
Original Statement
“Women who developed preeclampsia had a lower abundance of V. parvula in their oral microbiome (p = 0.04, Figure 4A), whereas the abundance of V. dispar was not significantly lower (p = 0.22, Figure 4A).”
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 design (case-control observational) can only show association, not causation. The claim uses 'had lower abundance' which correctly describes the observed association without implying causation.
