“…Sample sizes ranged from smaller studies (n<20 e.g., Hermanns et al, 2015;Saunders et al, 2017) involving perceptions of clinical tutors or faculty staff to larger student cohort studies (250≤n≤600, e.g., Holman & Hanson, 2016;Missildine et al, 2013;Saunders et al, 2017), with a median of 76 participants. The duration of interventions ranged from single-semester (Green & Schlairet, 2017;Mikkelsen, 2015;Yacout & Shosha, 2016) to year-long (Choi et al, 2015;Kim & Jang, 2017;Tune et al, 2013), to comparison of cohorts across two or more years of study (Posey & Pintz, 2017;Sari et al, 2017;Shatto et al, 2017).…”
