Table 2 Association of vital capacity with serum markers by multiple linear regression analysis

	β_est (95% confidence interval)	r	P
IL-15	-0.36 (-0.57 to -0.14)	-0.40	0.002
Inflammatory activity	1.65 (-6.45 to 9.75)	0.05	0.691
Anticentromer antibodies	19.49 (9.72 to 29.27)	0.46	<0.001
Anti-scleroderma-70 antibodies	-0.60 (-10.49 to 9.30)	-0.02	0.605

Coefficient of determination = 37%. Inflammatory activity describes an increased erythrocyte sedimentation rate, increased C-reactive protein or increased orosomucoid either alone or in combination.
