Table 3.
Changes in blood pressure and fasting plasma glucose between baseline and follow-up.
| Variables | Overall changes (95%CI) | Within-group changes | Between-group net changes (95%CI) | |
|---|---|---|---|---|
| BP and FPG not improved at follow-up | BP or FPG improved at follow-up | |||
| Systolic BP (mmHg) | 2.31 (2.04 to 2.59)a | 9.03 (8.62 to 9.43)a | −0.19 (–0.51 to 0.13) | 9.22 (8.65 to 9.79)a |
| Diastolic BP (mmHg) | 0.73 (0.54 to 0.92)a | 5.97 (5.72 to 6.23)a | –1.23 (–1.43 to –1.02)a | 7.20 (6.82 to 7.58)a |
| FPG (mmol/L) | 0.12 (0.09 to 0.15)a | 0.84 (0.78 to 0.90)a | –0.15 (–0.18 to –0.11)a | 0.99 (0.92 to 1.06)a |
BP, blood pressure; FPG, fasting plasma glucose; SD, standard deviation; CI, confidence interval.
Within-group changes with P value less than 0.001. The paired t test was used to compare the changes in blood pressure and fasting plasma glucose between baseline and follow-up within each subgroup. The independent two-sample t test was used to compare the within-group changes for patients with and without improved outcomes at follow-up.
