Unfortunately, an incorrect sentence from an early draft was inadvertently included in the final version of this manuscript. Thus, the sentence “Of the initial cohort, 78% and 55% of patients were alive and on bosentan monotherapy at 1 and 2 yrs, respectively” (final sentence in the left-hand column of page 246) should be removed in its entirety from the paper.
