We did univariate analysis to explore the risk factors of coronary artery lesion at 1 month after KD onset (defined as “coronary aneurysm” in the current study) and found age, incomplete KD, IVIG treatment, changes in lips and oral cavity, white blood cell count, platelet count, and levels of albumin were associated with the development of CA (Supplement Table 1). Here, ALB is linked to coronary aneurysm.
