Diagnostic evaluation of the critical values for esophageal varices (EV) indexes
| Disease | Index | Cutoff value | Cases (%) | Se (%) | NPV | NLR | Sp (%) | PPV | PLR |
| EV: Esophageal varices; HREV: High risk esophageal varices; Se: Sensitivity; Sp: Specificity; PPV: Positive predictive value; NPV: Negative predictive value; PLR: Positive likelihood ratio; NLR: Negative likelihood ratio; PSR: Platelet/splenic thickness ratio; SPT: Splenic thickness; US: Ultrasound score; PLT: Platelet; SVD: Splenic vein diameter; USWA: US-SPT-WBC-ALB (prediction model for EV); EVS: Esophageal varices score; SPA: SPT-ALB (prediction model for HREV). | |||||||||
