GSTM1 and esophageal varices: Additionally, the study found that patients with Child-Pugh class C cirrhosis had a significantly higher risk of early rebleeding after EVL when compared to patients with Child-Pugh class A. To further assess the relationship between Hb levels, Child-Pugh class, and the occurrence of early rebleeding after EVL in cirrhotic patients with esophageal varices, a nomogram prediction model was constructed.
