Model	-2LL	Δdf	Δ-2LL	AIC	BIC
Model 0	3538.07		-	3544.07	3557.41
Model 1	2491.72	1	1046.35***	2499.72	2517.51
Model 2	1636.05	1	855.67***	1646.05	1668.28
Model 3	1635.47	2	0.58	1649.47	1680.60

Notes. -2LL = -2Log Likelihood, Δdf = Change of degrees of freedom between the models, Δ-2LL = Change of -2Log Likelihood between the models, AIC = Akaike’s information criterion, BIC = Bayesian information criterion of Schwarz. Model 0 = random intercept model, Model 1 = additional fixed effect for slope, Model 2 = additional random effect for slope, Model 3 = additional fixed effects for group and interaction between group and slope.
