Ethics statement
This study was conducted using the SurveyMonkey Audience system. This platform is an online survey tool used to collect data from individuals across the US population. A pool of over two million people is maintained through an agreement wherein participants agree to take part in a survey, in exchange for SurveyMonkey making a donation of $0.50 to the charity of that individual’s choice. The SurveyMonkey algorithm then randomly assigns participants to surveys in a manner that creates a sample representative of the demographics specified by the investigator. As such, no additional specific IRB approval was required or obtained.
