Relation between the cumulated number of 2 mg pieces of nicotine chewing gum used in 71 quitters who had received nicotine chewing gum substitution for 12 weeks and were still abstinent after 26 weeks and the decrease in leucocyte blood counts at 12 weeks after smoking cessation
| Dependent variable | Intercept | Regression coefficient (SE) | r2 | p |
|---|---|---|---|---|
| Total leucocyte blood count | 2.1 | −0.1 (0.05) | 0.07 | <0.05 |
| Total neutrophil blood count | 1.6 | −0.05 (0.05) | 0.02 | NS |
| Total lymphocyte blood count | 0.6 | −0.05 (0.02) | 0.07 | <0.05 |
Bivariate regression analyses with the cumulated number of pieces of chewing gum was the independent variable. SE = one standard error; r 2 = square of the correlation coefficient.
