Reviewer's report:
Dear Editor
Thanks for sending me the manuscript entitled ‘ Investigating the role of vitamin D in treated
and refractory ulcerative colitis patients: a case-control study’ for revision
- The relation or impact of vit D and IBS was extensively studied but yet still important
- AS regard to abstract in result sector need to be claried or reformulated’ in the group of
ulcerative colitis patients was 45.88 (18.51) and in the resistant group was 41.30 (13.01).
Vitamin D; mean (std. dev.) in the group of ulcerative colitis patients was 24.96 (9.66) ng/mg and
in the resistant group was 27.70 (12.28) ng/mg, showing that there is no significant difference
in terms of serum vitamin D.’
What is meant by ulcerative colitis group (you mean the responders??)
- The study group was 24 , then in results was subdivided according to severity into 4 subgroups ;
one of them was 2 patients , how can we apply statistical analysis in such low number,
- Still it is important topic but need answers about patient numbers and sample size
thanks
