Reviewer’s report
Title: 
The effect of daily consumption of probiotic yogurt on liver enzymes,
steatosis and fibrosis in patients with nonalcoholic fatty liver disease (NAFLD):
study protocol for a randomized clinical trial
Version: 
0 
Date: 
11 Jan 2022
Reviewer's report:
Here, the authors intended to investigate role of probiotics in NAFLD treatment.
They described their study protocol very well. However, I recommend
describing diagnosis of NAFLD in details before publication. Moreover, the
authors should also mention the probe type they use for the evaluation of hepatic
steatosis.
