“…Most studies (39 of 57) were RCT [ 19 – 57 ], five were controlled non randomized clinical trials [ 58 – 63 ], four were prospective cohort studies [ 61 , 64 – 66 ], one was a retrospective cohort study [ 67 ], two was a case–control study [ 68 , 69 ], four were quasi-experimental [ 70 – 73 ], one was a pilot study [ 74 ] and one was a feasibility study [ 75 ]. The studies originated from 22 countries distributed across 4 continents (i.e., Americas, Europe, Asia and Oceania), most of which were high income countries [ 19 – 26 , 29 , 31 , 33 – 36 , 39 – 41 , 44 – 47 , 50 , 52 – 54 , 56 , 57 , 59 , 61 – 69 , 71 , 73 – 75 ] or upper-middle income countries [ 27 , 28 , 30 , 32 , 37 , 38 , 42 , 43 , 48 , 49 , 58 , 60 , 72 ], with only three studies conducted in lower-middle income countries [ 51 , 55 , 70 ]. The body of literature on this topic turned out to be quite recent, with 71.9% (41 of 57) of studies published between 2010 and 2022 and 22.8% (13 out of 57) between 2000 and 2009.…”
