  1. Abbreviation: PSQI, Pittsburgh sleep quality index.
  2. Data are presented as mean±standard error.
  3. One-way analysis of covariance for continuous variables were performed to assess whether there were significant differences among the groups of hypertension and no hypertension after adjusted for age, gender, BMI, current drinking status, current smoking status, tea consumption and exercise habits.
