M = Mean; SD = Standard deviation. Degrees of freedom 1 = 1 for all analyses; degrees of freedom 2 = 871 for all analyses. F = variance ratio; p = p-value
* = significant at p < .05 or p < .001
In this table, the negative sign (-) preceding the mean values just means “reduction”. Thus, the mean values presented in this table must be consider as “the mean of the number of cigarettes/days reduction”
