Numbers in parenthesis indicate number of subjects. Individual values below assay sensitivity not included. For reference, “clinically important” effects are indicated by Effect Size using the following established scale of Cohen’s d (Sawilowsky, 2009): moderate effect (>0.5), large effect (>0.8), very large effect (>1.2), and huge effect (>2.0). Bold values represent significant comparison of lower verses higher.
