The results were reported as follows: "Increased duration of e-cigarette use was associated with fewer cigarettes smoked per day and differing patterns of dependence to e-cigarettes contingent upon smoking history. Additionally, increased duration of e-cigarette use was associated with increased frequency of use; however, this finding became nonsignificant when current tobacco cigarette use was accounted for, suggesting that individuals may increase e-cigarette use frequency as they decrease cigarette use. Overall, e-cigarette users tended to decrease the strength of nicotine in their e-cigarette products regardless of duration of use."

Wynder et al. slightly lower bladder cancer risk among filtered cigarette smokers: "Smokers of filtered cigarettes had a slightly reduced risk of bladder cancer relative to smokers of nonfiltered cigarettes (odds ratio 0.64, 95% confidence interval 0.38 to 1.10 among male smokers; odds ratio 0.74, 95% confidence interval 0.37 to 1.48 among female smokers)."
