3.1. Characteristics of subjects
The demographic characteristics of the infants in the Yakson, GHT, and control groups are shown in Table 1.The results of X2 analyses and ANOVA comparing the infants in the three groups indicated that there were no significant differences among the groups in demographic variables of gender, the type of delivery, gestational age, birth weight, or Apgar scores. In a few cases, infants were removed from the study due to being discharged from the hospital, or because 24-hour urine was spilled during collection and could not be
analyzed.
