“…While retained participants at 12 months ranged from 28 to 60% in other publications, in our center, the retention rate at 12 months reached 84% [ 4 , 5 , 6 , 11 , 12 ]. The same results were observed at 3 months (56–87% vs. 90%) and 6 months (38–73% vs. 86%) [ 5 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 ].
