Transcapillary escape rate (TERalb) and urinary radioactivity after the three sodium interventions. (A) TERalb did not differ between low-sodium diet (7.0 [5.5 to 8.6]%) and high-sodium diet (7.0 [4.5 to 9.5]%) but increased significantly after saline infusion to 9.7 (7.8 to 11.6)%. *P = 0.04 compared to low-sodium diet. (B) Urinary radioactivity was also significantly increased after saline infusion. #P = 0.006 compared to low-sodium diet. *P = 0.006 compared to high-sodium diet. The data are represented as means and 95% CI (n = 12). The P values were derived from Bonferroni post hoc tests. CPM = counts per minute; kreat = creatinine in urine.
