A correlation test showed subsidiary differences between CTHRC1 and blood cells, including WBCs (r = −0.0088, p = 0.9685) (Figure 4A), neutrophils (r = 0.0105, p = 0.9661) (Figure 4B), basophils (r = 0.2432, p = 0.2522) (Figure 4D), and eosinophils (r = 0.2432, p = 0.2522) (Figure 4E) in the CKD group. Here, CTHRC1 is linked to chronic kidney disease.
