“…Fourteen (14/15) studies were peer-reviewed [ 5 , 10 , 19 , 21 , 22 , [30] , [31] , [32] , [33] , [34] , [35] , [36] , [37] , [38] ] and 1/15 of them was in-review [ 39 ]. Our investigation illustrated that the most of available reported evidences (13/15) were in the format of letter to editor, commentary and short reports [ 5 , 10 , 19 , 21 , 22 , [30] , [31] , [32] , [33] , [34] , [36] , [37] , [38] ], and only 2/15 were original articles [ 35 , 40 ]. None of the studies were interventional, and none of them followed the patients.…”
