Association of computed tomography densitometry with disease severity, functional decline, and survival in SSc-ILD.

A data supplement to the article "Association of Computed Tomography Densitometry With Disease Severity, Functional Decline and Survival in SSc-ILD" by Daniela Castillo Saldan, Cameron J. Hague, Darra Murphy and colleagues, that was published within the issue is presented. It shows baseline associations among quantitative computed tomography (qCT) variables such as skewness, kurtosis, and mean lung attenuation, visual fibrosis scores with pulmonary function, and unadjusted hazard ratios.
