Table 8.

DNMP descriptive statistics by group for 60-s delay. This includes the number of dogs tested (N) from each group, mean (real) percent error of each group, mean (real) number of trials performed by each group, 95% confidence interval, standard deviation, and number of dogs from each group that reached the criterion at the 60-s delay.

Group	N	Mean Percent Error	Mean Number of Trials	Upper 95% CI	Lower 95% CI	SD	Number of Dogs that Reached Criterion
Normal	1	0.5	30	---	---	---	0
MPS I treated	2 *	-----	-----	-----	-----	-----	0

* These dogs successfully reached the criterion at the 50-s delay but had reached the 80 trial maximum and, therefore, not eligible to be tested at the 60-s delay.
