S1PR1 knockdown protects endothelial cells from oxidized low-density lipoprotein-induced injury via reducing interleukin-1β and tumor necrosis factor-α expression

Figure 3 Receiver operating characteristic curve for prediction of coronary atherosclerotic heart disease based on a combination of sphingosine-1-phosphate receptor 1, interleukin-1β and tumor necrosis factor-α levels, the area under the curve was 0. 892 (95% confidence interval: 0.834-0.949). S1PR1: Sphingosine-1-phosphate receptor 1; IL: Interleukin; TNF-α: Tumor necrosis factor-α; AUC: Area under the receiver operating characteristics curve.
