Figure 1From: Membrane diffusion- and capillary blood volume measurements are not useful as screening tools for pulmonary arterial hypertension in systemic sclerosis: a case control studyA. The transfer factor of the lung for carbonmonoxide (TLCO%) in patients with systemic sclerosis-associated pulmonary arterial hypertension (SScPAH+) and in patients with systemic sclerosis without PAH (SScPAH-).B. The diffusion capacity of the alveolar capillary membrane as percentage of predicted (Dm%) in SScPAH+ and SScPAH-. Mean and SE are shown.Back to article page
