Hepatic fibrosis is a reversible wound repair response of the liver to chronic, non-self-limiting liver injury caused by various etiologies. It is very important to accurately diagnose liver fibrosis and predict the severity of liver fibrosis. Liver biopsy is still the gold standard of liver fibrosis, but it cannot meet the dynamic prediction of liver fibrosis severity and dynamic monitoring efficacy. Non-invasive, reproducible and rapid diagnostic indicators are urgently needed in clinical practice. China Chen et al.[1]A red cell volume distribution width-platelet ratio (RPR) model based on hepatitis B was proposed. Chen et al.[1]It was found that the diagnostic efficacy of this model in diagnosing patients with hepatitis B liver Fibrosis was better than other models such as Fibrosis-4 index (FIB-4) model and AST/platelet ratio index (APRI) model. However, the diagnostic efficacy of RPR for non-hepatitis B liver fibrosis and its clinical value in the grading diagnosis of liver fibrosis were not studied in depth.
