The primary end-point was the change in pulmonary vascular resistance (PVR) from baseline to week 20. Secondary end-points were changes in other haemodynamic parameters: 6-min walk distance (6MWD), Borg dyspnoea scale score, World Health Organization (WHO) functional class, EuroQol five-dimension five-level tool and N-terminal pro-brain natriuretic peptide.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      The change in PVR was \u221298.2\u00b1111.3\u2005dyn\u00b7s\u00b7cm\n                      <jats:sup>\u22125<\/jats:sup>\n                      and \u22124.6\u00b1163.6\u2005dyn\u00b7s\u00b7cm\n                      <jats:sup>\u22125<\/jats:sup>\n                      in the selexipag and placebo groups, respectively (mean difference \u221293.5\u2005dyn\u00b7s\u00b7cm\n                      <jats:sup>\u22125<\/jats:sup>\n                      ; 95% CI \u2212156.8 to \u221230.3; p=0.006).
