Statistical results of three exponential decay models. Pearson's R² shows similar predictive ability of each model for time of emergence from anaesthesia. Probabilities based on Akaike information criteria indicate the probability that a single model is the best one to fit experimental data, given the set of models being considered. AIC, Akaike Information Criterion.
