One study (Terzis 200919) reported 5 procedures; three studies (Gu 199217, Gu 199818, Gu 20027) reported 4 procedures; four studies (Hattori 200549, Chen 200730, Muhetidier 201138, Gao 201343) reported 3 procedures; six studies (Beaulieu 200628, Hierner 200731, Lin 201137, Sammer 201210, Chuang 201240, Wang 201346) reported 2 procedures; thus, there are 39 reference studies.
One study (Terzis 200919) reported 2 procedures; thus, there are 8 reference studies.
There are 56 patients underwent CC7 transfer to 93 target nerves. In addition, 46 patients underwent CC7 transfer to both MC and median nerves, 47 patients underwent CC7 transfer to both MC nerve and lower trunk, 10 patients underwent CC7 transfer to both median and triceps nerves, 1 patient underwent CC7 transfer to both radial and suprascapular nerves, and 1 patient underwent CC7 transfer to both MC and thoracodorsal nerves; thus actually there are 754 patients included in this systematic review.
