| Variable | Mean | SD** | P |
|---|---|---|---|
| Systolic | |||
| •Intervention | 123.6 | 14.81 | 0.001* |
| •Control | 142.2 | 15.82 | |
| Diastolic | |||
| •Intervention | 80.20 | 11.16 | 0.167 |
| •Control | 83.20 | 10.39 | |
*meaningful on α < 0.05 ** deviation standard
Illustrated that there was a significant difference of systolic blood pressure between intervention and control group (p < 0.05), but there was no differences of diastolic blood pressure between intervention and control group (p > 0.05)
