Figure 2

The size of the plotted squares reflects the relative statistical weight of each study. The numbers on the X-axis denote the standardized mean differences expressed as Cohen’s d. The horizontal lines denote 95% confidence intervals (CI) for the standardized mean differences. DUP, daily undulating periodization; LP, linear periodization; Std diff, standardized difference.
