Baseline characteristics of the study participants.
Table 2.
Eight year changes in the participants’ main characteristics and their correlation with baseline fractional reabsorption of sodium at the proximal and distal tubular level.

Changes in blood pressure for 1SD difference in baseline proximal and distal fractional reabsorption of sodium (linear regression analysis).
Fig 1.
Changes in systolic (A) or diastolic (B) blood pressure and fractional proximal reabsorption of sodium (proximal FR-Na), after 8 years of follow-up.
Proximal FR-Na expressed as changes in standard deviation (SD) (1SD = 6.7%). Solid line: model unadjusted (p< 0.01). Dash line: model adjusted for baseline age, BMI, systolic or diastolic blood pressure (rank), physical activity, alcohol intake, cigarette smoking, insulin sensitivity, and antihypertensive therapy at follow-up (p = 0.01).
