A second aim was to assess the role of cardiometabolic conditions such as obesity, hypertension, and dyslipidemia as potential effect modifiers.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>\n                      Data from 5733 US adults aged 30\u201364\u2009years and with complete periodontal examination were analyzed (NHANES 2011\u20132014). Participants were classified as having moderate\/severe periodontitis or mild\/no periodontitis according to the CDC\/AAP criteria as the outcome. The exposure was the TyG index, while both systolic (SBP), and diastolic (DBP) blood pressure were tested as mediators using parametric g\u2010formula. Analyses were adjusted for relevant confounders, namely, age, sex, ethnicity, poverty\u2010income ratio, and smoking, using inverse probability treatment weighting. Obesity status (based on a body mass index \u226530\u2009kg\/m\n                      <jats:sup>2<\/jats:sup>\n                      ), self\u2010report of hypertension and dyslipidemia (calculated based on the thresholds provided by National Cholesterol Education Program\u2010Adult Treatment Panel\u2010III) were tested as effect modifiers.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The findings showed the TyG index to be associated with increased odds of moderate\/severe periodontitis [odds ratio (OR), 95% confidence interval (CI)\u2009=\u20091.17 (1.11\u20131.23)], with 50% of the total effect mediated by SBP. Stratified analysis showed a stronger association in individuals with obesity, hypertension, and dyslipidemia compared to those without these conditions. However, in those taking anti\u2010hypertensive medications, the association was partially mitigated.
