| Group | Variable | Geometric Mean | 95% CI | Geometric Mean | 95% CI | Change,a % |

| Coaching | Urine cotinine (ng/mL) | 4.14 | (3.27, 5.18) | 3.13 | (2.48, 3.90) | −24.4 |
| Control | Child TLFB report, cigarettes/d | 2.21 | (1.93, 2.52) | 1.98 | (1.70, 2.32) | −10.2 |
| Coaching | Child TLFB report, cigarettes/d | 2.45 | (2.12, 2.84) | 1.73 | (1.55, 1.94) | −29.3 |
| Control | Parent TLFB report, cigarettes/d | 3.37 | (2.62, 4.28) | 1.67 | (1.24, 2.17) | −50.5 |
| Coaching | Parent TLFB report, cigarettes/d | 3.42 | (2.78, 4.17) | 1.39 | (1.02, 1.84) | −59.2 |
The geometric mean of raw values (and 95% CI) is given as an indicator of central tendency for these variables, which, due to skew, were log transformed for analyses. TLFB = timeline follow-back.
