Table 3

Univariate analysis of primary predictors of 3-year ILD-related events.

Variable	Hazard ratio	95% CI
Age	1.010	0.991–1.030	0.296
Sex (male)	1.218	0.472–3.140	0.680
CCIS	1.529	1.300–1.786	<0.001
Diagnosis of ILDs	2.154	0.914–5.077	0.085
ILD-GAP score	1.486	1.095–2.012	0.011
%FVC	0.975	0.952–0.998	0.036
%DLco	0.988	0.971–1.004	0.139

CCIS, Charlson comorbidity index score; G/A/P, gender/age/physiology; ILD, interstitial lung disease; %DLco, percentage predicted diffusion capacity of lung for carbon monoxide, %FVC, percentage predicted forced vital capacity.
