Note: ^a The best fitting model. AIC = Akaike information criterion, BIC = Bayesian information criterion, BLRT =  Bootstrap likelihood ratio test. Lower AIC, BIC values indicate a better fitting model. Higher entropy values indicate higher probabilities of each subject being assigned to a single profile. PV of the BLRT measures the statistical significance of the increase in model fit between the k−1 and k profile models.
