Absolute predictive performance in predicting COWA scores after a single 200 mg topiramate dose using the linear relative to the exponential models

	Linear model	Exponential model
Absolute predictive performance
MPE (95% CI)	4.32 (−4.92, 11.76)	3.45 (−3.51, 12.27)
MAPE (95% CI)	8.94 (4.92, 13.04)	9.13 (3.91, 13.2)

Twenty-seven observations were made in nine subjects. Abbreviations are as follows: CI, confidence interval; COWA, Controlled Oral Word Association; MAPE, median absolute prediction error (indicates the precision of the model in predicting the COWA scores as words per three trials); MPE, median predictor error (indicates the bias of the model in predicting COWA scores as words per three trials).
