“…Finally, two [24,25], two [26,27], and three [28][29][30] studies were performed by the same author, respectively; therefore, we chose the most informative and recent article or merged information from multiple publications (different publications that used the same study sample). Eventually, fourteen studies [25,27,28,[31][32][33][34][35][36][37][38][39][40][41] matched the selection criteria and were suitable for the meta-analysis. These included 9 retrospective studies [25,27,31,34,35,37,[39][40][41], 3 prospective nonrandomized studies [28,32,36] and 2 prospective randomized studies [33,38], with a combined total of 2249 subjects.…”
