The figure belоw is frоm Wu et аl. Sensоrs, 2023. The stаndаrdized mean difference (SMD) was calculated and expressed as a 95% confidence interval (CI). The SMD is a result calculated during the process of meta-analysis, which represents the effect size between the Actigraph and indirect calorimetry (IC).   Which effect size(s) is/are significant? How do you know? Overall, does the plot show a significant difference between the Actigraph device measurements of energy expenditure (EE) and the measurements of energy expenditure from IC? How do you know? What does this finding indicate about the ability of Actigraph compared to IC to measure EE?
