Figure 2.

Network plot of direct comparisons for different treatments for (A) muscle mass, (B) muscle strength, and (C) walking speed. The lines between nodes represent direct comparisons in various studies; the thickness of each line is proportional to the number of studies denoted on the line and indicates the connection between studies in terms of comparisons. The size of each node is proportional to the sample size of the participants involved in each specific treatment. AET, aerobic exercise training; AQET, aquatic exercise training; BFR, blood flow restriction; DIA, diet instruction and advisement; IMET, isometric exercise training; IMMR, intermittent multimeal replacement; MET, multicomponent exercise training; NMES, neuromuscular electric stimulation; RET, resistance exercise training; RMMR, regular multimeal replacement; RUMR, regular unimeal replacement; UC, usual care.
