Results are presented as percents for binary variables and as mean ± SDs for continuous variables other than ACR or as median (interquartile range) for ACR.

*

Systolic blood pressure at screening visit was used to determine trial eligibility. Baseline visit values are presented in this table.

For comparison of differences between the quintiles, all p values <0.001, except for “never smoked” (p=0.57). CVD = cardiovascular disease; ACR = albumin-to-creatinine ratio; GFR = glomerular filtration rate.
