Associations of the Triglyceride and Glucose Index With Hypertension Stages, Phenotypes, and Their Progressions Among Middle-Aged and Older Chinese

FIGURE 1. Flow chart of study participants (China Health and Retirement Longitudinal Study, China, 2011, 2015). Notes: SBP, systolic blood pressure; DBP, diastolic blood pressure; WC, waist circumstance; TG, fasting triglycerides; FPG, fasting plasma glucose; LDL-C, low-density lipoprotein cholesterol; HDL-C, high-density lipoprotein cholesterol; ISH, isolated systolic hypertension; IDH, isolated diastolic hypertension; SDH, systolic diastolic hypertension. Unrelated hypertension progressions: hypertension to normotension. Unrelated progressions of hypertension stages: stage 2 to stage 1, stage 2 to normotension, stage 1 to normotension. Unrelated progressions of hypertension phenotypes: ISH to normotension, ISH to IDH, IDH to normotension, IDH to ISH, SDH to normotension, SDH to ISH, SDH to IDH.
