**
We defined the following target BP values for antihypertensive therapy: <130/80 mmHg in the group aged 45–65 years;<140/90 mmHg in the group aged 65–80 years;<150/90 mmHg in the group aged ≥80 years;<140/80 mmHg in the group aged 45–65 years with chronic kidney disease; and<140/90 mmHg in the group aged ≥65 years with diabetes or chronic kidney disease.
