Fig. 2From: Equine osteoarthritis modifies fatty acid signatures in synovial fluid and its extracellular vesiclesDiscriminant analyses depicting the classification of fatty acid (FA) data in equine synovial fluid (SF) (panel A) and its ultracentrifuged extracellular vesicle-enriched pellet (EV) (panel B), and combined data (panel C) from control, contralateral (CL), and osteoarthritic (OA) fetlock joints based on discriminant functions 1 (on x-axis) and 2 (on y-axis). For each sample group, n = 8. In panel A, 16:1n-7, 20:0, 16:0i, 18:3n-3, and DMA 16:0 contributed to function 1, and 18:2n-6, 20:1n-9, 18:0, 20:2n-6, and 22:5n-3 contributed to function 2 with the highest separation power. In panel B, 22:5n-3, 18:3n-6, 20:2n-6, 24:0, and 18:0 contributed to function 1, and DMA 18:0, 17:0i, 20:3n-6, 18:3n-3, 20:0, and 16:0 to function 2, making them the most discriminative FAs between the diagnosis groups. In panel C, 22:0 (function 1), 16:0 (function 2), 18:2n-6, 17:0ai, 14:0, 17:0i, and 16:1n-7 (the last 5 in function 3) had the highest separation powerBack to article page
