Univariate linear regression and multivariate linear regression for the association between urinary sodium excretion and blood pressure in CKD patients

	Model 1			Model 2
	β	95% CI	p	β	95% CI	p
SBP	0.046	0.025–0.067	˂.001	0.020	0.000–0.039	.049
DBP	0.029	0.014–0.043	˂.001	0.015	0.001–0.029	.040
MAP	0.035	0.019–0.050	˂.001	0.016	0.002–0.031	.025

Model 1: unadjusted.

Model 2: adjusted for age, gender, BMI, eGFR, urinary protein excretion, history of antihypertensive drug.

A two‐tailed p < .05 was considered statistically significant.

Abbreviations: BMI, body mass index; CKD, chronic kidney disease; DBP, diastolic blood pressure; eGFR, estimated glomerular filtration rate.; MAP, mean arterial pressure; SBP, systolic blood pressure.
