A negative association indicates greater pre-meal brain activation in identified clusters (by contrast indicated) is associated with greater reduction in BMI z-score by FBT. A positive association indicates greater pre-meal brain activation in identified clusters (by contrast indicated) is associated with little or no change in BMI z-score by FBT. Cerebellum was not included in cluster analyses.
Harvard-Oxford Atlas identified regions of local maximum (*if local maximum appeared in white matter closest gray matter structure within cluster is listed),
Hemisphere of local maximum (L: Left, R: Right),
Montreal Neurological Institute (MNI) coordinates of peak location,
Brodmann area of local maximum,
maximum Z-score,
Other areas identified within the cluster (areas listed are ipsilateral to primary area unless otherwise indicated; L: Left hemisphere, R: Right hemisphere, B: Bilateral; regions in bold were included in functional-anatomic a priori regions of interest analyses (See Supplemental Figure 1). Z-statistic images were corrected for multiple comparisons with a cluster-threshold correction (individual voxel threshold Z=2.3, corrected cluster significant threshold P=0.05).
