Title: 
The Association Between Hypertension and The Risk Of Gallstone
disease: A Cross-sectional Study
Version:

Reviewer's report:
First and foremost, I would like to congratulate you for this study. Great effort.
Your study is simple and clear. Sample size is good and statistics are also very
clear. I would like to highlight some points which can be improved upon.
Introduction section could be a bit more comprehensive. In the introduction as
well as in discussion section, u mention of high-risk population and prophylactic
therapies. You should elaborate on these and provide references for the same. 
In the results section, you mention that blood pressure level correlates with
cholecystectomy in males. It was wrongly interpreted. The risk of
cholecystectomy was lowest in grade 3 hypertension compared to other groups
(odds ratio- 0.67) and also the risk of cholecystectomy in other groups was also
not significantly high compared to normotensive people.
In discussion section, you mention that hypertension and gall stones are not
significantly correlated because of low sample size. You could consider that
hypertension correlates with gallstone but not with symptomatic gallstone
disease which would require cholecystectomy. This could be one explanation.
You should provide more limitations
