  1. aOnly 723 cases with anti-CCP data were compared with a total of 1008 controls.
  2. bAll alleles and haplotype had statistically significant risk for anti-CCP positive RA compared with control [ORs (95% CI) 1.29 (1.11–1.50), 1.28 (1.10–1.51), 1.24 (1.07–1.43), 1.23 (1.06–1.42), and 1.29 (1.11–1.51) in order]
  3. cThe distribution of risk alleles and haplotype between antiCCP positive and negative groups were not significantly different.
  4. dP values of the risk alleles and haplotype in the anti-CCP negative group were not statistically significant level compared with control group.
