Body roundness index and self-reported oral health among US adults: Nonlinear patterns and an exploratory indirect association through the systemic immune-inflammation index
Evidence linking body roundness index (BRI) to self-reported oral health is limited. We examined this association, nonlinearity, subgroup differences, and an indirect association through the systemic immune-inflammation index (SII). This cross-sectional study included 14,656 adults from the 2009 to 2014 National Health...
