Cohen’s d effect size calculations were calculated for each drug dose in each phenotype separately. Percent change in PF intake at each drug dose is relative to each rat’s individual PF intake at saline; mean values for % change in PF intake represent ANCOVA-adjusted means, with PF intake at saline as the covariate.
