Results are presented as mean (standard deviation). Results show change within baseline blood pressure grouping over time. Annual blood pressure values presented are those of surviving patients with follow-up data recorded at each individual time point. Division by group describes the distribution of surviving patients with a documented blood pressure measurement between groups of blood pressure.
