Differences in systolic and diastolic blood pressure per unit per SD increase in salt intake and body weight (n = 288)

	SBP (mm Hg)			DBP (mm Hg)
	Mean difference	(95% CI)	P‐value	Mean difference	(95% CI)	P‐value
Salt intake per 1 g	1.73	(0.71 to 2.76)	0.001	0.48	(−0.21 to 1.17)	0.168
per 1 SD gram	4.13	(1.69 to 6.57)		1.15	(−0.49 to 2.79)
Body weight per 1 kg	0.52	(0.21 to 0.84)	0.001	0.27	(0.06 to 0.48)	0.013
per 1 SD kg	5.34	(2.12 to 8.56)		2.74	(0.58 to 4.90)

Estimated by general linear models adjusted for age, sex, height, smoking status, physical activity, comorbidity (cardiovascular, cerebrovascular, and renal diseases), diabetes mellitus, dyslipidemia, alcohol intake, and medication (antihypertensive agents and diuretics). Missing values were multiply imputed.

Bold value indicates significance at P < 0.05.
