Gene expression of IRX3 and FTO in blood samples of the intervention and control groups after 18 weeks. The fold change represents the ratio of the expression of the gene at the end of study to its expression at baseline. Data are presented as mean ± S.E.M. P-value was calculated using a two-tailed distribution independent t-test. *P < 0.05. As you note, gray is used for the graphs of the intervention group and black is used for the graphs of the control group
