Effect on Blood Pressure of Daily Lemon Ingestion and Walking

Table 3

Multiple regression analysis for the relationship between change rate of systolic blood pressure and blood citric acid concentration as dependent variables versus number of lemon intake and steps per day as independent variables.

	Systolic blood pressure (Δ%); (𝑃=0.32)		Citric acid (Δ%); (𝑃=0.01)
	𝛽 coefficient	𝑃 value	𝛽 coefficient	𝑃 value
Number of steps per day	−0.190	0.060	0.154	0.113
Lemon intake per day	−0.153	0.128	0.302	0.002
