“…6,22,4,21,28 There was no significant difference between the two groups (random: SMD 0.11 mm, 95% CI À 0.49-0.71 mm, P = 0.72). The test of heterogeneity among all studies showed heterogeneity (x 2 = 18.15, df = 4, P = 0.001; I 2 = 78%), therefore a random-effects model was used (Fig.…”

“…After selection according to the inclusion/exclusion criteria, eight articles qualified for the final review. 6,7,27,1,22,4,21,28 Two studies compared BSSO and IVRO for the retrognathic mandible, 27,1 and six studies compared two-jaw and one-jaw surgery with regard to PAS changes. 6,7,22,4,21,28 Characteristics of studies included Details of the studies included are shown in Tables 2 and 3.…”
