Table 2. Correlation values of arachidonic acid (AA) and its downstream metabolites based on six time points for the 12 subjects in the study.

Subject	5(S)-HETE vs AA	15(S)-HETE vs AA	11,12-DiHETrE vs AA	14,15-DiHETrE vs AA
1	0.98	0.83	0.72	0.79
2	0.75	0.92	0.92	0.93
3	0.57	0.59	0.89	0.83
4	0.86	0.80	0.70	0.69
5	0.71	0.76	0.96	0.92
6	0.25	0.69	0.95	0.93
7	0.67	0.90	0.91	0.86
8	0.84	0.82	0.78	0.69
9	0.88	0.91	0.98	0.91
10	0.66	0.70	0.98	0.86
11	0.98	0.86	0.93	0.93
12	0.84	0.65	0.97	0.89

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