Values are means with 95% confidence intervals in brackets. UNa, urinary sodium excretion rate; u-ENaCβ-CR, urinary ENaCβ excretion corrected for creatinine; V, urinary flow; u-AQP2CR, urinary AQP2 excretion corrected for creatinine; u-osm, urine osmolality; t-test: patients compared with controls, Student's t-test. § P < 0.001, HS vs. LS intake, paired samples t-test.
