Welcome to the screening questions for the Log2Lose study

This study is taking place at the University of Wisconsin Madison (UW-Madison) and Duke University.

The purpose of answering the screening questions is to see if you qualify for this study. These questions make sure that the people who participate in the Log2Lose study are able to do so as safely as possible. Please read these questions carefully and answer them the best you can. Doing so will make sure you can safely participate.

We will ask you to share some personal information, including questions about your past and present health conditions, medications you are taking, and alcohol and drug use. You will need to provide your first and last name, e-mail, age, race, ethnicity, and birth sex. You may also be asked for your complete contact information (address, phone and email) if you would like to be re-contacted about the study in the future.

Your responses will be kept private. Your personal information and responses are stored on secure servers that sit behind a firewall at Duke University. Your information is only available to members on the research team who have approval to view this information.

If you enroll in the study, all information you provide will be securely stored for up to 7 years after the study is complete. If you do not qualify, or decide not to participate, your age, birth sex, race, ethnicity, and information about why you did not qualify or why you declined to participate will be saved for up to 7 years after the study is complete; however, no identifying information such as your name or email address will be kept.

Completing the screening questions and participating in this study are voluntary. You can stop answering any questions at any time. Your refusal to answer questions will not negatively affect any relationship you have with UW-Madison or Duke University.

If you have any questions, please contact the Duke University research team at log2lose@duke.edu or the UW-Madison research team at log2lose@surgery.wisc.edu.
