“…We found 10 randomized clinical trials [ 60 , 61 , 62 , 63 , 64 , 65 , 66 , 67 , 68 , 69 ] and one quasi-experimental study [ 70 ] ( Table 3 ). All these studies were carried out in patients with CAD who underwent surgery for coronary artery bypass grafting (CABG) or were scheduled to receive this intervention; the two studies [ 71 , 72 ] of patients with CAD who were not going to undergo surgery were discarded due to the study performed by Darnley et al, which did not present a control group, and the study carried out by Muammer et al was exclusively in patients with metabolic syndrome. Eight of the studies selected compared IMT versus usual care [ 61 , 62 , 63 , 64 , 65 , 66 , 67 , 69 ], two of them analysed CT plus IMT versus CT [ 60 , 70 ] and one study compared AT + IMT versus AT [ 68 ].…”
