Table 4 Genotype and allele frequency among RA patients and controls

From: Anti-cyclic citrullinated peptide antibodies and paraoxonase-1 polymorphism in rheumatoid arthritis

Genotype Patients (n = 120) Controls (n = 90) P value Relative risk O.R.
QQ 70% (84/120) 68.90% (62/90) 0.862* 1.02 1.05
RR 17.5% (21/120) 20% (18/90) 0.644* 0.93 0.85
QR 12.5 (15/120) 11.10% (10/90) 0.758* 1.06 1.14
  Allele frequency    
Q 183 (76.26%) 134 (74.44%) 0.670* 1.04 1.10
R 57 (23.74%) 46 (25.56%)
  1. P value was calculated by χ 2 -test.
  2. P* value was not significant (P>0.05).
