Allelic frequencies of IL-33 rs1929992 gene polymorphism and their relationship with odds of CSU.

Gene	rs	Minor Allele	MAF (%)		HWE p-Value a	OR [95% CI]	p-Value b
			CSU Group	Non-CSU Group
IL-33	1929992	A	31.25	17.35	0.3197	2.17 [1.10, 4.27]	0.024 *

MAF: minor allele frequency; HWE: Hardy–Weinberg Equilibrium; ^a calculated in non-CSU group; OR: unadjusted odds ratio; 95% CI: 95% confidence interval; ^b estimated from Chi-squared test; statistical significance was achieved if p < 0.05. * significant result: p < 0.05.
