There was some evidence (P = 0.03) for a difference between CHD cases and controls for a cytokine activity pathway (CCL5, C5, PF4, and CCL16), and some (P = 0.04) for an acute inflammatory response pathway (ORM1, ORM2, C2, CFHR1, MBL2, AHSG), whereas there was no evidence of corresponding differences between stroke cases and controls. This evidence concerns the gene PF4 and Stroke.
