Table 3.
The number of children included after applying exclusion criteria for each scan separately. BMI percentiles were calculated using the CDC standards for age-sex-weight-height-specific cut offs (Kuczmarski et al., 2000). BMI = body mass index; Y1 = Year 1; QC = Quality control; Structure = included cortical thickness, surface area, subcortical volume, Diffusion Tensor Imaging (DTI) which included fractional anisotropy (FA) and mean diffusivity (MD); FD = framewise displacement; ROI = Region of interest. fMRI = functional magnetic resonance imaging; rsfMRI = resting state functional magnetic resonance imaging; SST = Stop Signal Task.
