This was a small, single-group, open-label study with no randomized control or comparator arm, and its primary efficacy measure—change in pulmonary vascular resistance—was a hemodynamic surrogate rather than a direct clinical outcome. Registry results were not posted at the time of grading; the key result shown was recovered from the cited external source.
