Table 2.
Adjusted (Weighted) regression models estimating the odds of believing that HTPs are less harmful than cigarettes among smokers in Japan in 2018.
| User Group All Users (N = 3600) |
HTPs Are Less Harmful % | Odds Ratio | 95% CI | |
|---|---|---|---|---|
| Lower CI | Upper CI | |||
| Exclusive Smokers (n = 2614) | 43.8% | Reference | ||
| Concurrent Users (n = 986) | 62.1% | 2.1 | 1.7 | 2.5 |
| Concurrent Users (n = 986) | ||||
| Frequent HTP Users (n = 548) | 71.7% | 1.9 | 1.4 | 2.6 |
| Infrequent HTP Users (438) | 57.1% | Reference | ||
| Concurrent Users (n = 982) | ||||
| Predominant Smokers (n = 528) | 58.8% | 0.5 | 0.4 | 0.7 |
| Concurrent Daily Users (n = 396) | 73.2% | Reference | ||
| Concurrent Non-daily Users (n = 58) | 56.4% | 0.5 | 0.2 | 0.9 |
Outcome: Less harmful versus equally/more harmful/do not know. HTPs: Heated tobacco products; CI: Confidence interval.
