Reviewer's report:
Introduction is well written clarifying the background and the objective. Methods
should be included before the result. Information regarding statistical analysis
needs to be included. Result should include only the findings from your study,
not the methods. The data presented in tables should not be repeated in the text
unless the results are pertinent. Also Table 1 title of socio-demographic
characteristics of patients doesn't match the variables in the table except age and
Male. The percentage of the male should be written along side the number as
well. Clinical significance of the findings should be explained more if there is
any, regardless of statistically non significant findings. Some of the discussion
points are great. However researches and articles contributing more in this field
should be included with the more analytical discussion. The flow of the
sentences should be improved.
