Table 1: The descriptive statistics, such as mean and standard deviation of each measurement. Difference between the groups were assessed by a Willcoxon Rank Sum test. Data are shown as mean ± S.D. A p value of <0.05 was considered statistically significant, and individual p values in preD2 and D2 group were shown as compared with D0 group.
