Effect estimates (β) and probability values (p) are presented for the relationship between SASSI and basal renal plasma flow in univariate and multivariate models. Model 1 is adjusted for age. Model 2 additionally adjusts for race, gender, body mass index, and the presence of diabetes. Model 3 additionally adjusts for systolic blood pressure. In those participants older than the median (47 years), there is a significant inverse association between SASSI and RPF that is significant through multivariate adjustment until systolic blood pressure is added.
