As described in PRISMA flow diagram (Fig. 1), a total of 9,685 studies were assessed in our systematic search. After the removal of duplicates and the screening of titles or abstracts, 93 manuscripts were eligible to be thoroughly reviewed for inclusion and exclusion criteria. Finally, 36 studies, encompassing a population of 16,005 patients, formed the scope of the analysis [32,33,34,35,36,37,38,39,40,41,42,43,44,45,46,47,48,49,50,51,52,53,54,55,56,57,58,59,60,61,62,63,64,65,66,67].
