(A) MU, Music Therapy; TAU, Treatment As Usual; YO, Yoga Therapy; EX, Exercise Therapy; OC, Occupational Therapy. (B) When therapies are connected with an un-interrupting line, they have been directly compared in an RCT (for example, between YO and TAU). (C) The thickness of lines represent the number of studies that investigated this comparison. (D) An indirect comparison between YO and TAU is demonstrated by the dotted line. The comparison YO and TAU can be indirectly estimated via the loop YO to EX, from EX to TAU.
