Abnormal splenic artery diameter/hepatic artery diameter ratio in cirrhosis-induced portal hypertension

Figure 1 Receiver operating characteristic curve analysis for identifying the optimal cutoff values. A: Abnormal internal diameter of the splenic artery; B: Abnormal splenic artery internal diameter/proper hepatic artery internal diameter (S/P) ratio for patients with cirrhosis and portal hypertension. Binary logistic regression showed that the areas under the receiver operating characteristic curve were 0.667 (95%CI: 0.581-0.753) and 0.633 (95%CI: 0.572-0.694) for the internal diameter of the splenic artery and S/P ratio, respectively (both, P < 0.05). The optimal cutoff values were identified to be > 5.19 mm for abnormal internal diameter of the splenic artery and > 1.40 for abnormal S/P ratio.
