“…Eighteen studies [ 24 , 30 , 34 , 36 – 39 , 44 , 46 , 49 , 53 , 54 , 56 , 58 , 60 , 62 , 64 , 69 ] were developed in a face-to-face format and were then transformed to digital format but did not use a virtual learning environment (i.e., there was no platform for content management, lesson planning, engagement, administration, communication). In 21 studies [ 25 , 26 , 29 , 31 , 33 , 35 , 40 , 42 , 45 , 47 , 48 , 50 – 52 , 55 , 57 , 63 , 65 , 67 , 71 , 72 ], the authors did not provide information about the learning environment, and in five studies [ 27 , 41 , 43 , 59 , 61 , 68 ], the authors only mentioned that an e-learning/online learning system or a learning management system was used. One study reported that a shareable weblink was used but offered no specific information [ 32 ].…”
