The study’s reliance on a small sample size (81 respondents) raises concerns about the generalizability of its findings, especially given the exclusion of 44 participants without a detailed discussion of their characteristics. Additionally, the exclusion of an opt-out option in the discrete choice experiment may lead to forced choices that do not align with real-world clinical decision-making, potentially inflating attribute importance. The significant discrepancies between WTP estimates in preference and WTP spaces suggest possible methodological weaknesses in the assumptions regarding cost sensitivity. I would thank the authors for sharing their thoughts on this issue.
