Fig. 3From: Circulating secretoneurin level reflects angiographic coronary collateralization in stable angina patients with chronic total occlusionReceiver operating characteristic curve analysis of detecting good collateralization. An optimal cutoff of serum SN 190.12 pmol/L predicted good coronary collateralization (AUC 0.662, 95% CI, 0.624 ~ 0.699; P<0.001; sensitivity 38.98% and specificity 90.71%)Back to article page
