As a result, the set of 28 publications remained ( [28], [35], [52], [40], [27], [57], [63], [51], [50], [65], [42], [38], [31], [47], [62], [46], [30], [34], [37], [61], [36], [44], [53], [39], [32], [45], [29]), which was used for executing the snowballing iterations. Finally, 11 new publications were identified with the snowballing methodology: ( [48], [49], [55], [43], [64], [33], [41], [60], [56], [58], [54]), which were added to the final set of 39 papers.…”
