Risk of (a) stroke recurrence, (b) combined vascular events, (c) death, and (d) poor outcome according to the index of adipose tissue specific insulin resistance (Adipo-IR). The solid line indicates adjusted hazard ratio/odds ratio and the dashed lines the 95% confidence interval bands. Reference is the minimum value of Adipo-IR (0.032). The vertical dashed lines indicate the first, second, third and fourth quintile of Adipo-IR. Data were fitted using a Cox/logistic regression model of restricted cubic spline with 5 knots (the 5th, 25th, 50th, 75th, and 95th percentiles) for Adipo-IR, adjusting for potential covariates
