aFor mixed-gender cliques we also included gender as control variable (girl = 0/boy = 1). The effect of gender was .08*** (.01) for the models with physical aggression and −.08*** (.01) for the models with relational aggression
bThe decrease in χ2 deviance for models 1 of boys’ and girls’ cliques is compared with the deviance of the empty model, and of mixed-gender cliques compared with the deviance of the model including only gender. Model 2 is compared with model 1
