(A) Proportion of correct responses with 95% confidence intervals. (B) Odds ratios (OR) between performance on DNMS at second test period vs first test period, and (C) ratios of odds ratios (ROR) in performance on DNMS across time in treatment groups relative to Veh. Results are separated by delay length (15 sec, 30 sec, 60 sec, 120 sec, and 600 sec delays). Group designations (Veh, E2, Delay, Withdrawn) as in Figure 1. *** p < 0.001, ** p < 0.01, * p < 0.05. p-values in (C) were corrected using Dunnett’s method for comparing parameters from three separate experimental groups (E2, Delay, and Withdrawn) to the control group (Veh).
