The treatment Tx has a causal effect of around 2 Hamilton points on the mean of the study population. If we control for the mean ~ SD relationship when estimating the variability between treatment and control, we only measure the direct effect of treatment on variability, while no such control (as with the VR effect size) measures the total effect of the treatment on outcome variability.
