Fig. 1From: Indoleamine 2,3 dioxygenase (IDO) level as a marker for significant coronary artery diseaseA Box plot of indoleamine 2,3 dioxygenase (IDO) activity values at baseline in the insignificant coronary artery disease (CAD) group, and in the significant CAD [single-vessel disease (SVD)/double-vessel disease (DVD)/triple-vessel disease (TVD)] group. B Box plot of high-sensitivity troponin T (hs-TnT) values at baseline in the insignificant CAD group, and in the significant CAD (SVD/DVD/TVD) group. C Box plot of high-sensitivity C-reactive protein (hs-CRP) values at baseline in the insignificant CAD group, and in the significant CAD (SVD/DVD/TVD) group. D Box plot of tryptophan values at baseline in the insignificant CAD group, and in the significant CAD (SVD/DVD/TVD) groupBack to article page
