Equations for hierarchical multiple regression models for dietary magnesium intake for intervention and control schools¹

School designation	Model equation
Intervention	Changes in dietary magnesium intake = −9.25 + (−0.30*BMI percentile) + (−0.86*glucose) + (−1.02*insulin) + (0.11*dietary calcium intake) + (0.001*total energy intake) [r = 0.38, R2 = 0.14, F(4,1040) = 42.98]
Control	Changes in dietary magnesium intake = −1.41 + (−0.36*BMI percentile) + (−0.10*glucose) + (−0.21*insulin) + (0.11*dietary calcium intake) + (0.001*total energy intake) [r = 0.35, R2 = 0.12, F(4,1131) = 38.64]
