Oral Health and Its Association With Gut Microbiota Diversity in Older Post‐Stroke Inpatients
In this registry-based cross-sectional study, poorer oral health (higher ROAG score) was associated with lower gut microbiota α-diversity (Shannon index). Given multiple outcomes and no preregistered analysis plan, these findings are exploratory/hypothesis-generating and require confirmation in independent cohorts and longitudinal studies.
