From: An umbrella review of efficacy of digital health interventions for workers

a Forest plot of d-Health interventions on objectively measured step counts in RCTs that used no intervention as the control, and b forest plot of those in RCTs that used non-d-Health interventions as the control. The error bars in the plot represent the 95% CI. Each square within the plot corresponds to the standardized mean difference in step counts observed across different studies. The size of the squares reflects the relative weight of each study in the analysis. The hollow diamond displays the overall effect size.
