Table 3. Correlation values of linoleic acid (LA) and its downstream metabolites based on six time points for the 12 subjects in the study.

Subject	9(S)-HODE vs LA	9,10-DiHOME vs LA	13(S)-HODE vs LA
1	0.61	0.51	0.65
2	0.92	0.85	0.91
3	0.60	0.55	0.61
4	0.81	0.86	0.83
5	0.64	0.58	0.65
6	0.93	0.73	0.87
7	0.78	0.53	0.72
8	0.75	0.63	0.81
9	0.85	0.89	0.89
10	0.69	0.74	0.74
11	0.99	0.97	0.98
12	0.88	0.95	0.90

The pseudo-steady-state approximation implies that LA and its four downstream metabolites are correlated as given by Equation (6) in the text.
