In a previous issue of the World Journal of Gastroenterology, we have read the article by Li et al with great interest. We would like to thank the authors for their comprehensive contribution. However, it is our wish to make minor criticism over the present study from the perspective of methodology.
Core tip: Hepatitis B virus infection is still one of the leading causes of cirrhosis and hepatocellular carcinoma. Liver biopsy is the gold standard method to assess the severity of liver fibrosis. However, there are several limitations of liver biopsy, including its invasive nature, small tissue sample size, and subjective grading system. Nowadays, noninvasive parameters have been utilized to evaluate liver histology. Additionally, ultrasound-based techniques, such as acoustic radiation force impulse have gained popularity in assessing liver fibrosis. Herein, we aimed to make a minor criticism regarding this study.
