Trajectory patterns of blood pressure change up to six years and the risk of dementia: a nationwide cohort study

Four latent trajectories of systolic blood pressure (SBP) for Chinese older people. The latent growth mixture model was used to estimate the SBP trajectories. Class 1, normal SBP; class 2, stabilized SBP; class 3, elevated SBP; and class 4, persistently high SBP.
