Table 2.
Prospective Association Between Wave 1 Nicotine Product Harm Perceptions and Wave 2 Choice of Nicotine Product used as an Aid for Last Quit Attempts Among Baseline Daily Smokers Smoking 10+ Cigarettes per day who had made a Quit Attempt by Wave 2 (N = 1289^).
| Wave 1 Predictors | Wave 2 NRT use vs other/no aids a aRRR (95% CI) |
Wave 2 NVP use vs other/no aids b aRRR (95% CI) |
Wave 2 Both NRT & NVP use vs other/no aids c aRRR (95% CI) |
|---|---|---|---|
| NRT Relative Harm Perception | |||
| Much Less harmful | 3.79 (2.16, 6.66) *** | 1.51 (0.88, 2.61) | 1.96 (1.03, 3.73) * |
| Somewhat Less harmful | 1.98 (1.15, 3.42) * | 1.47 (0.89, 2.05) | 1.16 (0.62, 2.15) |

Note: NRT = Nicotine Replacement Therapy, NVP = Nicotine Vaping Products;
aRRR = adjusted Relative Risk Ratio which estimates the likelihood of the outcome (e.g., NRT use vs other/no aids) for a variable, holding all other variables in the model constant; CI = Confidence Intervals;
Significant at p < .05
p < .01
p < .001.
Total N reduced due to the exclusion of the small number of Don’t Know responses on ethnicity and education from analysis.
Multinomial logistic regression model comparing between any use of NRT either exclusively or in combination with other aids but exclude NVP for LQA and no aid/other aids as the reference.
Multinomial logistic regression model comparing between any use of NVP either exclusively or in combination with other aids but exclude NRT for LQA and no aid/other aids as the reference.
Multinomial logistic regression model comparing between use of both NRT and NVP for LQA either exclusively or in combination with other aids and no aid/other aids as the reference.
All models adjusted for the other variable in the table, along with age, gender, income, education, ethnicity, country, knowledge of smoking harms and nicotine harm belief.
