The odds ratio of logistic regression to identify the association between elevated hs-CRP and smoking status classified as urinary cotinine levels

Variable Model 1a Model 2b Model 3c Model 4d




OR 95% CI P-value* OR 95% CI P-value* OR 95% CI P-value* OR 95% CI P-value*
Urinary cotinine (ng/mL)
<50 (non-smoker) 1 1 1 1
≥50 (smoker) 0.887 -0.293–0.054 0.174 0.905 -0.276–0.079 0.270 0.945 -0.235–0.124 0.534 1.046 -0.138–0.230 0.635

Multivariable models were adjusted for body mass index, HDL cholesterol, WBC count.

OR, odds ratio; CI, confidence interval; hs-CRP, high-sensitivity C-reactive protein; HDL, high density lipoprotein; WBC, white blood cells.

aModel 1: unadjusted (urinary cotinine). bModel 2: adjusted for body mass index. cModel 3: Model 2 plus HDL. dModel 4: Model 3 plus WBC.

P-values for the multivariable adjusted. *Statistically significant (P<0.05).
