Table 4 Simple logistic regression analyses determining the odds ratios for different risk factors for rheumatoid arthritis

From: The PTPN221858C/T polymorphism is associated with anti-cyclic citrullinated peptide antibody-positive early rheumatoid arthritis in northern Sweden

  Odds ratio 95% confidence interval
Anti-cyclic citrullinated peptide antibodies 145.00 58.72–358.09
Smoking 5.10 4.02–6.46
HLA-shared epitope 2.04 1.43–2.91
T-carriage 1.79 1.41–2.28
