Study & Design

Study Type: Interventional

Study Design: Not specified

Primary Outcome Measures

Name	Time	Method
<p>The primary study parameter is the correlation coefficient of liking of<br /><br>e-liquid flavors through smelling versus liking of e-liquid flavors through<br /><br>vaping, for smokers as well as for non-smokers.</p><br>

Secondary Outcome Measures

Name	Time	Method
<p>Secundary study parameters are:<br /><br>- Difference in correlation coefficient of liking by smelling and liking by<br /><br>vaping between smokers and non-smokers.<br /><br>- Correlation coefficients of intensity, familiarity, and irritation of<br /><br>e-liquid flavors by smelling versus vaping, for smokers as well as for<br /><br>non-smokers.<br /><br>- Average (mean+SE) liking, intensity, familiarity, and irritation of the<br /><br>e-liquids used in this study, including differences (p-value) between<br /><br>e-liquids, for smelling as well as for vaping. In addition, a distinction will<br /><br>be made between male and female research subjects.<br /><br>- Slope and intercept for the relation between liking by smelling and liking by<br /><br>vaping, within research subjects.<br /><br>- Correlation coefficients between average liking, intensity, familiarity, and<br /><br>irritation, for smelling as well as for vaping.</p><br>
