Comparison of apelin concentration, systolic and diastolic blood pressures before and after treatment

	Group	Baseline treatment	After	P*	P**
Apelin, ng/mL	Telmisartan	0.27±0.13	0.34±0.18	0.009	0.922
	Amlodipine	0.32±0.17	0.38±0.17	0.013
SBP, mm Hg	Telmisartan	154±7	122±8	<0.001	0.658
	Amlodipine	154±10	123±10	<0.001
DBP, mm Hg	Telmisartan	92±6	74±9	<0.001	0.271
	Amlodipine	95±9	76±8	<0.001

Values are expressed as mean±standard deviation. DBP - diastolic blood pressure; SBP - systolic blood pressure.
