As indicated in Table 3, Spearman’s correlation analysis showed that gender (r = 0.504, p = 0.012), age (r = 0.611, p = 0.009), duration of fever ≥10 days (r = 0.579, p = 0.005), Hb (r = 0.623, p = 0.031), and CRP (r = 0.558, p = 0.018) were associated with the CAL in children with Kawasaki disease. Here, GSTM1 is linked to Kawasaki disease.
