CI = confidence interval; FCGR2A = Fc gamma receptor II a; iKD = incomplete type of Kawasaki disease; KD = Kawasaki disease; OR = odds ratio; RAF = risk allele frequency.

^*The RAFs (risk allele: A; non-risk allele: G) for FCGR2A were 0.758 and 0.761 for the male and female controls, respectively; ^†The p<0.05 was considered significant and is denoted in bold.
