## 4 Results and Discussion
### Solution Layer Weights  
As illustrated in Figure 4, within the Basic Functionality B1 level, Effectiveness (C1, 0.3440) holds the highest weight, followed by Learnability (C7, 0.1521), Easy to use (C3, 0.1785), and Efficiency (C4, 0.1479). Next, we have Satisfaction (C6, 0.0533), Errors (C5, 0.0482), and Convenience (C2, 0.0760). These rankings indicate that, within Basic Functionality, users primarily focus on whether the platform can accurately and effectively perform its intended functions. Additionally, users care about the ability to quickly learn how to use a platform and the efficiency of the service. Therefore, when optimizing the basic functionalities of a medical website, priority should be given to enhancing the platform's effectiveness, ease of learning, and usability.

As shown in Figure 5, within the Design and Interface B2 level, the indicator User-Centric Design (C12, 0.5529) carries the highest weight, followed by Navigation (C9, 0.1295), Feedback (C8, 0.1172), Interactivity (C13, 0.0873), Consistency (C11, 0.0720), and finally, Screen Design and Layout (C10, 0.0410). These rankings highlight that, in Design and Interface, users are most concerned with whether the interface is user-centric, i.e., whether the website provides an interactive experience that meets user needs and expectations. Additionally, good navigation and timely feedback are crucial factors in enhancing usability, playing a significant role in ensuring a smooth and intuitive user experience. Therefore, when optimizing the design and interface of a medical website, the principles of user-centric design should be prioritized, along with ensuring good navigation and effective interactivity, to enhance the overall user experience.  
As depicted in Figure 6, within the Features and Technology B3 level, Searchability (C16, 0.4272) holds the highest weight, followed by Redundancy (C17, 0.2352), Controllability (C18, 0.1282), Remote Presentation (C15, 0.0970), Responsiveness (C19, 0.0620), and finally, Accessibility (C14, 0.0503). These rankings indicate that, in Features and Technology, users are most concerned about their ability to quickly and accurately find the information and services they need. Additionally, users care about the redundancy and controllability of the webpage, i.e., avoiding redundant functions on the platform and the degree of control users have over platform operations, such as font size and selecting specific operational processes. Therefore, when optimizing the features and technology of a medical website, priority should be given to enhancing the searchability of information and reducing the redundancy of the interface.  
As shown in Figure 7, within the Trust and Security B4 level, Property Protection (C24, 0.3447) has the highest weight, followed by Credibility (C21, 0.3370), Privacy Protection (C22, 0.2172), Content Relevance (C23, 0.0653), and finally, Readability (C20, 0.0358). These rankings demonstrate that, in Trust and Security, users are most concerned about the protection of their assets. Additionally, the credibility of the information provided by the website and privacy protection are key factors that users consider, which are directly related to the site's reputation, user trust, and privacy. Therefore, when optimizing trust and security on a medical website, priority should be given to strengthening measures for
