研究概览
简要总结
The goal of this survey is to investigate the participants' preference for a specific screening/diagnostic tool to detect and assess gastro-esophageal cancer.
The main question it aims to answer are:
- Which diagnostic modality is preferred by patients and the general population?
- Which features of the diagnostic test are most detrimental in the decision-making for one or the other modality?
- Are geographical differences present in regard to the preference for a diagnostic modality?
Participants will be asked to complete a survey of 20-25min, including a brief intake regarding their socio-economic status. This approach will allow us to correct for confounding factors.
