NCT ID: NCT04996940

Last Updated: 2023-09-13

Results Overview

Using the questionnaire scale "Intentions for Future Use" How much each participant intends to use the products in the future. Scale: "Think about the product you just used. If this was the only flavor available, how likely would you be to try this flavor again? 1. Extremely unlikely 2. Unlikely 3. Neutral 4. Likely 5. Extremely likely The range of observed responses from participants for both groups was 1-5. Not all participants completed all study measures so the number of respondents is lower than enrolled.
