Table 1. NMR Signals Assignments of Metabolites with Significant Changes in Serum on Days 15 and 30, with Their Fold Change Values, p Values, FDR p Values, VIP Values and Correlation Coefficient Values (r).
a
Fold
change values were colored
according to log 2(fold) using color bar: 
red
and blue indicates increasing and decreasing concentration
of each group compared to NC.
b
The absolute of correlation coefficient |r| obtained from PLS-DA model, the cutoff of |r| was set to 0.707.
c
The p values were obtained from independent samples t-test. The chemical shifts in boldface are used in calculating the relevant integrals and p values (*p < 0.05, **p < 0.01).
d
Multiplicity: s-singlet; d-doublet; t-triplet; q-quartet; dd-doublet of doublets; m-multiplet.
e
The FDR p values were calculated from p values, the p values with no significant difference (P > 0.05) were not calculated and expressed by “/”.
