*
Cochran-Armitage trend test two-sided P values to examine if flavor preference varied linearly across age groups at the baseline survey and at the follow-up survey, respectively:
Tobacco: P = 0.04 and P < 0.0001.
Menthol or mint: P = 0.46 and P = 0.65.
Fruit: P = 0.01 and P = 0.16.
Chocolate/candy or other sweets: P = 0.65 and P = 0.07.
