Multiple linear regression models of the predictors of CPD, expired CO, and plasma COT

Dependent variable: CPD (n = 700), R2 = 0.17
PredictorB95% CIStandardized βP
Plasma COT0.150.11-0.190.32<0.001
Expired CO0.090.03-0.150.120.004
Mentholated cigarettes−0.03−0.06-0.00−0.070.05
BMI0.08−0.04-0.200.050.21

NOTE: Nonmentholated cigarette users and males were coded as 0. Variables that were not normally distributed (CPD, expired CO, plasma COT, BMI) were log-transformed in the analyses.

Abbreviation: 95% CI, 95% confidence interval.
