General information about the trial
|
|||
Main objective of the trial |
The aim of the study is to test the hypothesis that treatment with riociguat or sildenafil in patients with NDI
caused by AVP2R mutation improves the symptoms by reducing diuresis
|
||
Protection of trial subjects |
Patients were hospitalized for the first two days of each intervention to enable close monitoring of side-effects. For the rest of each intervention, patients had daily check-ups where symptoms and side-effects were monitored and handled.
|
||
Background therapy |
None | ||
Evidence for comparator |
Not applicable. The effect of the two interventions was evaluated by comparing baseline values to similar values after each intervention. | ||
