First, we utilized the utility scoring system developed in China to compute the utility values of QLU-C10D and EQ-5D-5L in the three datasets and conducted a comparison between them. To assess the ceiling and floor effects of both scales, we analyzed the data from the initial measurement. Scatter plots were employed to visually represent the correlation between QLU-C10D and EQ-5D-5L in the first dataset, while the Spearman correlation coefficient was used to compare the correlation between C10D and 5L. Despite C10D being a scale specific to cancer, both C10D and 5L serve as tools for evaluating health-related quality of life (HRQoL) and share some common dimensions. Therefore, it is expected that a high level of consistency would be observed between them.
