Key clinical point: Clinicians shouldn’t rely on pulmonary function tests alone to screen for interstitial lung disease in patients with early diffuse cutaneous systemic sclerosis, and should combine them with high-resolution CT.
Major finding: Pulmonary function tests had a positive predictive value of 64%-74% and an negative predictive value of 61%-70%.
Study details: A multicenter, prospective cohort study of 212 adults with early diffuse cutaneous systemic sclerosis at 11 U.S. academic medical centers between April 2012 and January 2019.
