- Values are the absolute numbers of genotypes or alleles with frequencies in percent given in parentheses. P values were calculated using chi-squares test with 2 × 2 contigency tables (alleles) or 2 × 3 contigency tables (genotypes) for comparison of frequencies of the indicated markers in the patients compared with the controls.
- RA = rheumatoid arthritis; wt = wild type.
