Figure 2.

Forest plot of treatment success rates of fall prevention, frailty mitigation, and chair-stand improvement during the overall follow-up period. Each study result is represented as a point estimate (square box) with 95% CI (horizontal line). The study results plotted on the right-hand side indicate effects in favor of protein supplementation (PS) plus exercise training (ET), and the combined effects are plotted as black diamonds. 95% CI = 95% confidence interval; IV = inverse variance; Fixed = fixed-effects model; CG = control group; Con = control; MET = multicomponent exercise training; PLA-S, placebo supplement.
