Relationship between the changes in the major metabolite levels by Pearson’s correlation analysis. 𝑟, correlation coefficient. The changes in lysophosphatidylcholine (lysoPC) 16:0 levels were positively related to those of lysoPC 15:0 (𝑟=0.90, 𝑃<0.001) and lysoPC 18:0 (𝑟=0.76, 𝑃<0.001), while that of lysoPC 18:0 was closely related to that of lysoPC 15:0 (𝑟=0.77, 𝑃<0.001). The change in the lysoPC 18:2 level was closely related to that of lysoPC 18:0 (𝑟=0.81, 𝑃<0.001), while that of lysoPC 18:1 was related to that of lysoPC 18:2 (𝑟=0.69, 𝑃<0.001). The change in the proline level was related to those of tryptophan (𝑟=0.53, 𝑃<0.001) and phenylalanine (𝑟=0.55, 𝑃<0.001).
