When PIR was examined as a categorical variable, individuals in the highest PIR tertile exhibited a 0.1 lower TyG index compared to those in the lowest tertile in the crude model(β = -0.10, 95% CI:-0.13~-0.06, P < 0.001); Following adjustments in both Model 1 and 2, the association between PIR and TyG remained marginally significant (β =-0.17, 95% CI:-0.21~-0.13, P < 0.001 and β = -0.11, 95% CI:-0.15~-0.07, P < 0.001, respectively).
