Table 3 Linear and logistic regression analyses for the combined effect of cigarette smoking and metabolic syndrome on hs-CRP

From: Cigarette smoking worsens systemic inflammation in persons with metabolic syndrome

Median linear regression coefficients (95% CI)
  Smokers with no MetS Non-smokers with MetS Smokers with MetS
Model 1 0.10 (-0.06, 0.26) 0.70 (0.60, 0.80) 1.3 (1.06, 1.56)
Model 2 0.12 (-0.04, 0.29) 0.73 (0.62, 0.84) 1.39 (1.13, 1.66)
Model 3 0.11 (-0.05, 0.27) 0.69 (0.58, 0.79) 1.29 (1.03, 1.55)
Logistic regression odds ratio for elevated hs-CRP (95% CI)
  Smokers with no MetS Non-smokers with MetS Smokers with MetS
Model 1 1.27 (0.97, 1.66) 1.83 (1.56, 2.16) 3.70 (2.59, 5.28)
Model 2 1.28 (0.97, 1.67) 2.09 (1.76, 2.48) 4.24 (2.95, 6.08)
Model 3 1.30 (0.99, 1.71) 2.02 (1.69, 2.41) 4.00 (2.77, 5.08)
  1. Model 1: unadjusted; Model 2: adjusted for age and sex; and Model 3: adjusted for age, sex, LDL, total cholesterol, statins and anti-hypertensive medications Hs-CRP: high sensitivity C-reactive protein; and MetS: metabolic syndrome elevated hs-CRP = hs-CRP >3 mg/L.
