![]() In addition, it has poorer discriminatory power in the lower ranges of the score. This raised the need for the development of new scores that lack those limitations. However, it has several limitations as it can be affected by causes other than liver diseases. However, these two models have some drawbacks for example ascites and encephalopathy in CTP scores are subjected to inter-observer variability While MELD score has the advantage of not being subjected to inter-observer variability like in the case with the CTP score. A lot of prognostic models were developed such as Rockall, Glasgow-Blatchford, Child– Turcotte-Pugh (CTP), Model for end-stage liver disease (MELD) and chronic liver failure-sequential organ failure assessment (CLIF-SOFA) scores, with The CTP score and MELD score being the best-known prognostic models. This raised the need for the development of sensitive and specific risk prediction models for high-risk patients with AVB in order to decrease this mortality rate. Despite multiple procedures are available to control bleeding, still AVB is associated with high morbidity and mortality in affected patients as it is associated with a 6-weeks mortality rate of 10 to 20%. One of the complications of acute decompensation of cirrhosis that occurs due to increased portal hypertension and hepatic dysfunction is acute variceal bleeding (AVB), which is considered a leading cause of death in patients with cirrhosis. ![]()
