Identification of anatomy, hemispheric location (L/R), coordinates (x, y, z) in MNI space (mm), analysis of covariance (ANCOVA) results statistics, and effect size for the difference within clusters in which relapsers showed significantly lower RSS than abstainers within the (A) middle occipital gyrus RSS map. ANCOVA results showed a trend of lower RSS in relapsers than abstainers within the (B) insula RSS map
