Figure 2. Multiple-adjusted restricted cubic spline regressions were used to analyze the association between RDW and risk of HT, (A) symptomatic HT (B) after IVT placed at three knots (at the 10th, 50th, 90th percentiles). The solid line represents adjusted odds ratios, while the shaded area represents 95% confidence intervals (CI). Reference point for RDW was the median (13%). RDW, Red cell distribution width; HT, hemorrhagic transformation.
