Note. CI = confidence interval.

^aContinuous, individual-level independent variables were centered about the grand mean.

^bContinuous neighborhood-level independent variables were centered about the neighborhood-level mean.

^cContinuous school-level independent variables were centered about the school-level mean.

*P < .05; **P < .01; ***P < .001.
