Stepwise logistic regression model for smoking topography measures predicting abstinence, controlling for nicotine dependence, treatment group, and cigarette type (n = 113)

PredictorsAbstinence
OR (95% CI)
P
Nicotine dependence (Fagerström Test for Nicotine Dependence 0-10)1.01 (0.81-1.26)0.94
Treatment group (0 = patch, 1 = spray)1.11 (0.45-2.75)0.82
Cigarette type (full flavor/medium = 0, light/ultralight = 1)0.35 (0.14-0.89)0.03
Mean time between puffs (interpuff interval)1.06 (1.00-1.11)0.03
Mean puff volume0.95 (0.91-0.98)0.01
Mean puff velocity0.87 (0.74-1.02)0.09
Mean Vmax1.12 (1.02-1.24)0.02
  • NOTE: ORs are expressed as per unit change in the smoking topography measures.
