Table 5. Haplotype analysis for genotypes of HLA-DP/DQ and IgAN risk.

Haplotypes	Case (freq.)	Control (freq.)	OR (95%CI)	p
AAA	11.50 (0.041)	50.15 (0.051)	0.81 (0.42~1.56)	0.526019
AAG	64.41 (0.230)	174.03 (0.178)	1.42 (1.03~1.96)	0.033938
AGG	40.29 (0.144)	95.49 (0.097)	1.59 (1.07~2.36)	0.020488
GAG	73.31 (0.262)	131.98 (0.135)	2.34 (1.69~3.24)	1.67E-07
GGA	7.91 (0.028)	58.67 (0.060)	0.46 (0.22~0.99)	0.041992

OR: odds ratio; CI: confidence interval; IgAN: IgA nephropathy.

Order of HLA haplotype block: rs3077 (minor allele A), rs9277535 (minor allele A) and rs7453920 (minor allele A).

Bold values are statistically significant (p < 0.05).
