I would just point out to be wary of studies done in less developed countries.
India, Brazil, Turkey...how advanced are their medical systems? Just a note to consider...I haven't looked at them yet.

Also, look at the journal. A good journal will take a submitted paper and send it to qualified peers in the field for review and comments. This helps to get a reliable and well constructed paper into the journal. Some are better reviewed than others...J of Vascular Surgery- Probably pretty reliable. Others? World J of Surg? Ever heard of that one? Who knows if someone really reviewed that articla before publication.


Defeinitely interested inthe UCLA article.
