Figure 3. Urinary Sodium Excretion After Volume Expansion With BNP Pre-Treatment.
Urinary sodium excretion in (A) normal control subjects, (B) PSD subjects, and (C) PDD subjects at baseline, 30 min after volume expansion, and 60 min after volume expansion, after placebo (open bars) or subcutaneous B-type natriuretic peptide (SQ BNP) (solid bars) administration. *p < 0.05, ‡p = 0.07 versus baseline, and †p < 0.05 versus placebo as measured by t test using a Bonferroni correc- tion for multiple comparisons.
