NLevel1 = 1261–1283, NLevel2 = 513–521; k = number of parameters in model. Time was coded continuously (T1 = 0, T2 = 1, T3 = 2). Method of estimation: full maximum likelihood. The reported estimations are fixed effects with standard errors. Varying degrees of freedom due to selectively missing values. ∗∗∗p < 0.001, ∗∗p < 0.01, ∗p < 0.05.
