About this trial
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.

Trial outcomes
Primary outcomes
The rate of contribution of diagnostic features to the preference of participants
A part-worth analysis, expressed as percentage, from a discrete choice experiment (questionnaire) will assess the features that are most important to the participants
The percentage differences in preference of participants between geographical regions
Differences in preferences will be compared between different geographical regions using chi-squared or McNemar's test
Secondary outcomes
Assess the rate patient-level demographics influence the importance of a test feature, expressed as an odds ratio
Assess the influence of demographic characteristics on the decision-making process using a multivariable logistic regression model, providing odds ratios.
Assess the rate of trade-off demonstrated as odds ratio between cancer-related mortality reduction and costs
Based on an anticipated cancer detection and cost, we will assess the willingness-to-pay using a multivariable logistic regression, providing odds ratios.
