Correlation of systolic pulmonary arterial pressure (PASP) at 25 Watts and PASP at rest. Cutoff values are 45 mm Hg for PASP at 25 Watts and 40 mm Hg PASP at rest. Circles represent patients without pulmonary hypertension (PH) verified by right heart catheterisation (RHC); squares are patients with manifest associated pulmonary arterial hypertension according to RHC as gold standard. PASP at rest with a cutoff value of 40 mm Hg would have missed five manifest PH patients; PASP at 25 watts with a cutoff value of 45 mm Hg would have missed only one patient with a slightly lower specificity. CI confidence interval
