The comparison between the subjects’ weight at baseline with those at 6 months (T6) and 12 months (T12) and its relationship with FTO gene according to dominant genetic model

			p-value
FTO rs9939609 T > A	TT	TA + AA	Genotypea	Timeb	Interactionc
Baseline	96.8 (82.2, 101.9)	95.0 (82.9, 112.9)	0.720	< 0.001	0.022
T6	96.5 (79.5, 100.5)	96.2 (80.0, 111.5)
T12	88.8 (81.5, 91.8)	94.5 (77.4, 110.4)

Statistically significant value is given in bold

Data are expressed as median and interquartile range. Probability that the effect of nutritional intervention on weight is influenced by:

^a time, for each variable, the differences have been tested between baseline, T6 and T12 of the two Genotypes

^b groups, for each variable, the differences have been tested between Genotypes over times

^c Probability that the effects of nutritional intervention is greater in one distinct group (interaction Time *genotype)
