From: Rheumatoid arthritis is an independent risk factor for multi-vessel coronary artery disease: a case control study

Variable Unadjusted OR (95% CI) P Adjusted ORa(95% CI) P
RA diagnosis 1.73 (1.03, 2.91) 0.04 1.97 (1.15, 3.36) 0.01
History of hyperlipidemia NA NA 2.56 (1.35, 4.85) 0.004
Age (per year increase) NA NA 1.05 (1.02, 1.07) 0.002
Sex (female relative to male) NA NA 0.40 (0.23, 0.67) 0.001
  1. aAdjusted model is the result of a forward selection procedure, and adjustment was made for age, sex and history of hyperlipidemia.
  2. CI, confidence interval; NA, not applicable; OR, odds ratio; RA, rheumatoid arthritis.
