Title: Magnetic resonance elastography in staging liver fibrosis in non-alcoholic fatty liver
disease: A pooled analysis of the diagnostic accuracy
Version: 0Date: 09 Feb 2020
Reviewer: Federico Salomone
Reviewer's report:
The meta-analysis by Liang et al. falls in the important field of non-invasive assessment of fibrosis
in NAFLD. The aim of the study is relevant. Overall the analysis is well performed, results areconvincing and the manuscript is well-written. I have only minor concerns.-The forest plot are notclear, please improve the quality of images.-It has been showed that non-invasive scores such asNAFLD fibrosis score are predictive of mortality [quote PMID 30111756]. Please briefly discussthat although the diagnostic accuracy of MRE is high as showed by results, it would be importantin the future studies to assess the predictive value of MRE for mortality, the "real" outcome forpatients with NAFLD.
