Subjects are dependent observations between T1 and T4 with valid measurements at T2
Bold - significant p-value < 0.05
b = regression coefficient, estimates of intervention group
OR = odds ratios for the intervention group
1Serving sizes (examples below):
Snacks = 1.5 dl of crisps or cheese doodles
Sweets = about 1.5 dl of sweets or 4 pieces from a chocolate bar
Cakes = a small bun or 5 small biscuits
Ice-cream = a small ice cream bar or 1 dl ice-cream
Drinks = 1.5 dl
