Associations between anxiety and laboratory measures of inflammation for adolescent healthy controls (n = 88)^a

Dependent variable	β, unstandardized coefficient	P, dependent variable significance	95% CI for β, unstandardized coefficient
Log serum IL‐6, pg/ml (n = 53)	0.000	0.961	–0.005, 0.005
Log serum CRP, mg/liter (n = 52)	0.074	0.636	–0.003, 0.005
Log serum cortisol, mg/ml (n = 48)	0.000	0.921	–0.003, 0.003
Log stimulated IL‐6, pg/ml (n = 49)	0.004	0.052	0.000, 0.008

^aData were analyzed using multiple linear regression models. Independent variable was anxiety. Age, sex, and time of day of blood sample collection (e.g., morning, afternoon) were controlled for in all models. Serum interleukin 6 (IL‐6), serum C‐reactive protein (CRP), serum cortisol, and lipopolysaccharide‐stimulated IL‐6 were log transformed; anxiety was not log transformed. 95% CI = 95% confidence interval.
