 ^{a}Missing data were excluded (n = 51). Among 39 haplotype structures, 7 haplotypes with a frequency of at least 1% in both the patients and controls are presented; the total frequency of the other haplotype structures was 46 (6%) for controls and 30 (3.8%) for patients. Logistic regression models were used to calculate ORs
 ^{b}Computed for the estimated coefficient of each haplotype in the logistic regression
