Review report of "Metabolic Status and Lifestyle Factors ass ociated with Gallbladder Polyps: A 
Covariance Structure Analysis"  
 
 
The work is good, it shows the metabolic status and lifestyle factors in association with 
gallbladder polyps. The authors will do well to explain in details the proper pathway or 
mechanism r esponsible for the link between metabolic and lifestyle factors in association with 
gallbladder polyps (discussion session).

Line 150; page 7: Recast this statement "Physical activity was investigated the freque ncies and 
duration of participants attending light, moderate, or  vigorous physical activities in the past 
months"  
 
 
Authors should explain the method of collection of blood (serum or plasma?) in methodology 
session.  
 
 
Overall, the study contributed to the exi sting knowledge and also give a link to the effect of 
lifestyle factors in relation to development of gallbladder polyps, but more rigorous future 
studies have to be done on these high rising incidence. This study is just a pointer.
