Relationship of Triglyceride-glucose Index and Common Carotid Artery Intima-Media Thickness in Patients with Ischemic Stroke. Odds ratios and 95% confidence intervals derived from restricted cubic spline regression, with knots placed at the 5th, 35th, 65th, and 95th percentiles of the distribution of triglyceride-glucose index levels. The reference point is the midpoint (8.01 mg/dL) of the reference group from categorical analysis. Odds ratios were adjusted for the same variables as model 3 in Table 2. cIMT indicates carotid artery intima-media thickness. Panel A: Abnormal mean cIMT (P for linearity = 0.005); Panel B: Abnormal maximum cIMT (P for linearity = 0.027). Abnormal mean and maximum cIMT were defined as cIMT values ≥ 1 mm
