Reviewer’ s report
Title: Predictors of advanced fibrosis in elderly patients with biopsy-confirmed nonalcoholic fatty
liver disease: The GOASIA study
Version: 1Date: 07 Feb 2020
Reviewer: David Kleiner
Reviewer's report:
The authors have generally addressed my comments, but I think that I may not have been
completely clear about my request to show the distribution of the non-invasive results. The newFigure 2 plots the mean of the non-invasive fibrosis scores against the stage, which really doesn'tshow the distribution of the individual scores in each category at each fibrosis stage. A box plot(https://en.wikipedia.org/wiki/Box_plot) is probably the most concise way of showing thedistribution of data although there are others. This type of data presentation gives readers a muchgreater appreciation for the spread of the data.
