Numbers indicate the number and percentage of subjects in each diagnostic group showing maximal intake and self-reported liking, wanting and sweetness for each of the five solutions, arranged in order of increasing aspartame concentration. Intake was determined by summing intake of each solution across the three trials and self-report measures were determined by averaging VAS measure of each variable across the three trials.
One subject with AN reported identical maximal wanting values to the 0.03% and the 0.08% solutions. The remaining AN subject reported zero values for wanting of all solutions and is not included in this table. Data from NC subjects have been previously published (1).
