Some subjects may report different eating speeds throughout their check-ups during the study period. In addition, subjects who underwent four to six check-ups may have different reported eating speeds during their intermediate phase (second to fifth check-ups); in these subjects, the eating speeds during the intermediate phase were categorised in the following order of priority: slow, normal and fast. For example, a subject with both slow and fast eating speeds reported in the second to fifth check-ups would be reflected as having a slow eating speed during the intermediate phase.
*Subjects with only two eating speed measurements during the study period.
†Subjects with only one eating speed measurement during the study period.
