“…Our search identified 14 studies ( Table 4 ) which met our criteria (see Figure 1 ), including a total of 4.913 trans persons ( 17 , 36 – 40 , 42 – 45 , 47 – 50 ). In almost all cases, participants' inclusion was assessed through self-identification as “transgender,” “trans men” or “trans women” ( 17 , 37 – 40 , 42 – 46 , 48 , 50 ). While seven studies included mostly trans women ( 37 , 38 , 40 , 45 – 48 , 50 ), four included more trans men ( 17 , 42 , 44 ) and in one study most participants identified as non-binary [Transgender participants were considered non-binary if they reported a gender identity that was anything other than exclusively male or female, (40, p. 339)].…”
