  1. Data are mean (SD), SD standard deviation, BMI body mass index, SDS-BMI standard deviation score of body mass index, SSRT stop signal reaction time measured in ms, AV adjusted value defined as the average number of pumps excluding balloons that exploded
  2. a In the group with complete data, at T0 scores on the SSRT were not available for three participants and scores on the AV were not available for two of them
