CD36 and inflammatory bowel disease: Figure 4 shows mean values (±SE) of the oleic acid threshold determined in IBD patients and HC subjects; data are also shown according to PROP taster status and the rs1761667 (A/G) polymorphism of CD36. One-way ANCOVA showed that the oleic acid threshold of IBD patients was higher than that of HC subjects (F1,136 = 44.779, p < 0.000001) (Figure 4A).
