Abstract
This letter critically evaluates Jiang et al 's article on the differentiation of benign and malignant liver lesions using Emax and platelet count. Despite notable findings, significant methodological and interpretative limitations are identified. The study lacks detailed assay conditions for Emax measurement, employs inadequate statistical methods without robust multivariate analysis, and does not provide clinically relevant threshold values. The nomogram's reliance on Emax as a major diagnostic contributor is questionable due to attenuation in hepatocellular carcinoma patients with cirrhosis. Moreover, the study's limitations, such as selection bias and confounding factors, are not adequately addressed. Future research should adopt more rigorous methodologies, including prospective studies with larger cohorts and standardized protocols for biomarker measurement, to enhance validity and clinical applicability.
