  1. The deviance and Akaike’s Information Criterion (AIC). The smaller the deviance and the AIC the better the model fits the data.
  2. *P < 0.05, **P < 0.001.
  3. Variance estimates of random effects and goodness-of-fit statistics are reported for each model. For assessing goodness-of-fit the models are compared to the corresponding individual growth model. For each parameter its mean and the mean of its standard errors (SE) over the five imputed datasets are reported.
