Figure 2

Effect of exercise intervention on overall quality of life in PD patients. The black diamond represents the standardized mean difference (SMD) for each trial with the arms reflecting 95% confidence intervals (CIs). The x axis scale indicates the range of 95% CIs of the trials. The size of the shaded box reflects the relative weight of each study. The unfilled diamond represents the overall SMD of the trials, and its width represents the confidence interval.
