Title: Clinical characteristics, CT Signs, and Pathological Findings of Pyrrolizidine Alkaloids-
induced Sinusoidal Obstructive Syndrome: a retrospective study
Version: 1Date: 12 Dec 2019
Reviewer: David Kleiner
Reviewer's report:
I understand from the review responses that there was limited information available in follow-up.
This is unfortunately the nature of this field. Once patients feel better, they have no incentive toreturn to the treating physician. Nevertheless, since recovery from drug and herbal-induced liverinjury has become an important part of both diagnosis and characterization of the natural history ofthe injury I would encourage the authors to summarize what information is available on theircohort and to include it in the manuscript. Even the limited amount of data provided in theresponse would be of value to future readers.
