Title:Blood ammonia levels in liver cirrhosis: a clue for the presence of
esophageal varices.
Version: 2Date:6 February 2009
Reviewer: Roberto de Franchis
Reviewer's report:
Minor essential revisions
1)An important piece of information which is missing is the number of patients
with NH4 levels above the 42 microMoles threshold who had no varices. This
would give a measure of the number of unnecessary endoscopies that would
have been made if the threshold was adopted.
2) The English form has somewhat improved, but the paper still needs revision
by a native English speaker, since the form is awkward in several points.
Level of interest: An article whose findings are important to those with closely
related research interests
Quality of written English: Needs some language corrections before being
published
Statistical review: No, the manuscript does not need to be seen by a
statistician.
