The number of studies by continent was distributed as follows: Europe, four studies (Simonen et al, 2011;De Angelis, 2013;Laihonen and Sillanpa ¨a ¨, 2014;Ikonen, 2020), Asia, four studies (Hamidi et al, 2016;Najmi et al, 2017;Tamanna and Sharma, 2019;Ganguly et al, 2020), North America, two studies Sibbald et al (2016), Parast and Golmohammadi (2019) and Australasia, one study (Massingham et al, 2018). It is also interesting to note that no study offered a perspective on the international context.…”
