FIGURE 1.

Smoothed plot for multivariable-adjusted HRs in a natural-log scale for total stroke risk (A), ischemic stroke risk (B), hemorrhagic stroke risk (C), and stroke mortality (D) (number of events = 2991, 2750, 241, and 609 for panels A–D, respectively) in association with dietary glycemic index in the Shanghai Women’s Health Study (n = 64,328). The ln-HRs were estimated by using the restricted cubic spline proportional hazards model with 3 knots at the 5th, 50th, and 95th percentiles of glycemic index. The 10th percentile was treated as the referent. Point estimates are indicated by solid lines and 95% CIs by dashed lines.
