I know who to contact if I have any questions about the study in general. In the screening tests, we found that you met the criteria for this common cold study. We are studying the effect of inhaling warm, humidified air when you have the common cold. Whether or not you take part in the study is your choice. If you don't want to take part, you don't have to give a reason, and it won't affect the care you receive. If you do want to take part now, but change your mind later, you can pull out at any time.
