* Plus–minus values are means ± SD, with the 95% confidence intervals. NS denotes not significant. Independent-sample t-tests (with 95% confidence intervals) were used to compare group means at Baseline. † The values shown are unadjusted means with the 95% confidence intervals. p values were calculated with analysis of covariance. Point estimates and estimates falling within the 95% confidence interval were generated from independent t-tests for group differences. Because the subjects of the study have different chronic diseases, the trend of blood indicators before intervention is not the same. This will mask the effects of the intervention during statistical analysis. Therefore, covariance analysis was used to analyze the difference between the two groups at 6 weeks after testing the adjusted covariates. A two-sided p value of less than 0.05 indicated statistical significance. ‡ Total cholesterol, Normal value 3–5.2 mmol/L or so. § The normal blood pressure range is: systolic blood pressure (SP) 140–90 mmHg, diastolic blood pressure (DP) 90–60 mmHg. ‖ Triglyceride: The normal range is: male 0.44~1.76 mmol/L; female 0.39~1.49 mmol/L. High-density lipoprotein cholesterol: male <40 years old 0.9~1.83 mmol/L (30~59 mg/dL), female <40 years old 1.1~2.0 mmol/L (33~77 mg/dL); triglyceride: the normal range is: male 0.44~1.76 mmol/L; female 0.39~1.49 mmol/L.
