Adjusted hazard ratios of outcomes according to baseline TyG index. a Stroke; b Ischemic stroke; c Intracerebral hemorrhage. Data were fitted using a Cox regression model of restricted cubic spline with five knots (at the 5th, 25th, 50th, 50th, 75th and 95th percentiles) adjusting for potential covariates. The reference point for TyG index was the median of the reference group. Red lines indicate adjusted hazard ratio, and blue lines indicate the 95% confidence interval bands
