Current screening algorithms are hampered by low positive predictive values. Outcome measures that could add to performance characteristics would be welcome.

In 3 cross-sectional studies, SSc-PAH was found to be unequivocally inversely associated with capillary density (p = 0.001 and p &lt; 0.05) and associated with the presence of a severe NVC pattern (p = 0.03 and p &lt; 0.05).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion.<\/jats:title><jats:p>This is the first systematic literature review investigating the role of NVC in SSc-PAH using standardized description, to our knowledge.
