Interestingly, excluding participants with active treatments strengthened the association between TyG index trajectories with arterial stiffness; relative to the low-stable group, the high-increasing group had the highest odds for arterial stiffness (OR = 3.57 (1.45, 9.63), P = 0.037), and the moderate group showed a borderline significant association with arterial stiffness (OR = 3.54 (1.00, 9.59), P = 0.051) after adjustment for various confounders.
