ICC, Intra-Class Correlation. Empty cells indicate that the variables did not enter into the model. Model 0, Null model; Model 1, Univariable association; Model 2, Multivariable associations, only Individual-level variables; Model 3, Multivariable associations, only school-level variables; Full model, Multivariable associations, Individual-level and school-level variables. Significant odds ratios (ORs) are shown in bold (p ≤ 0.05) only for the Full model.
