Cohort	Sample size	Univariate analysis		Multivariate analysisa
		β (95% CI)	P value	β (95% CI)	P value
New	270	6.75 (2.70, 10.81)	0.001	4.84 (0.84, 8.83)	0.01
Combined	615	5.25 (1.67, 8.84)	0.004	5.35 (1.86, 8.83)	0.003

Abbreviations: BMI, body mass index; CI, confidence interval; SNP, single-nucleotide polymorphism.

^aAdjustment made for age, sex, race, BMI, disease state (hypertensive vs. normal and diabetic vs. hypertensive and normal). The SNP rs2540923 was stratified by comparing the GG group to the AG + AA group.
