The incidence of cognitive decline served as the primary outcome. CTI was calculated as: CTI\u2009=\u20090.412\u00d7 Ln (CRP [mg\/L])\u2009+\u2009Ln (TG [mg\/dl] \u00d7FPG [mg\/dl])\/2. Cognitive performance was assessed in 2020 using the Chinese Mini-Mental State Examination (MMSE). Logistic regression and complementary approaches were used to analyze associations.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Over the 9-year follow-up, a significant positive association between CTI and cognitive decline risk was observed. After multifactorial adjustment, individuals in the highest CTI quartile (Q4) demonstrated a 34% elevated risk relative to the lowest quartile (Q1) (HR\u2009=\u20091.34, 95%CI: 1.10\u20131.63; p\u2009=\u20090.004). A monotonic dose-response gradient was evident (p\u2009=\u20090.005), with restricted cubic splines confirming linearity (p\u2009=\u20090.025).
