Longitudinal change during follow-up of systemic sclerosis: correlation between high-resolution computed tomography and pulmonary function tests

The objective of this study was to determine the correlation between functional and radiological longitudinal change in patients with systemic sclerosis–associated interstitial lung disease (SSc-ILD), and to test the OMERACT definition of clinically meaningful progression of pulmonary function tests (PFTs) for the prediction of ILD radiological evolution. We retrospectively retrieved high-resolution computed tomography (HRCT) studies and PFTs...
