Out of the total of 1422 a group of 1311 subjects completed and returned the daily questionnaire to self-record mild symptoms. In contrast to the observed symptoms and AE, self-reported mild symptoms were recorded if a particular symptom was experienced by the same person more than 3 times during the fasting period. The observed symptoms and AE were documented during the daily nurse visit and/or the medical visit for all subjects. The same subject could mention more than one symptom or AE.
