Model selection with the data of Study 1.

MOI Models 2–9 were fitted to the pooled data of Study 1 [9]. We give estimates of model parameters with the 95% CI in parenthesis, and an asterisk indicates the lower and upper 95% CI limits coincide with the estimate parameter value. For each model we also provide the negative log likelihood (NLL), Akaike information criterion (AIC), the difference between a given model and the best-supported model in AIC (ΔAIC), and the Akaike Weight (AW). Overall, Model 3 is the best-supported model, although there is also some support for Model 6, which combines the single mechanisms incorporated in Models 3 and 4. The improvement in model fit (NLL) between Models 6 and 3 is, however, minimal.
