Supplement File 1-Supplement File - Income-Based Analysis of Health Security in Western Asia through an Integrated GHSI, MCDM, and Clustering Model.pdf

Summary: This supplementary material supports our study titled "Income-Based Analysis of HealthSecurity in Western Asia through an Integrated GHSI, MCDM, and Clustering Model." Additionalcontext and data tables are provided to enrich the main analysis and findings. The document is dividedinto four primary sections. It begins by outlining the key health security criteria used to evaluatecountries: prevention, detection and reporting, rapid response, health system adequacy, commitmentto international norms, and overall risk environment. These criteria were applied to decision matricesfor 2019 and 2021. This section also includes the development of matrices that determine the weightsof the health security criteria, rank countries, and group them by performance. Comprehensive scoresare presented for different income groups, including high-income (HIC), upper-middle-income(UMC), lower-middle-income (LMC), and low-income (LIC) countries. The second section detailsthe results of the D-CRITIC calculations used to establish the relative importance of health securityindicators for Western Asian nations, broken down by income category (LIC, LMC, UMC, HIC) forboth 2019 and 2021. The third section explores the application of the D-CRITIC-CoCoSo model inranking the health security performance of these countries for the same years. It includes normalizedvalues, weighted comparability sequences, and final rankings that highlight the changes over time.The final section presents the clustering analysis, which segments countries based on their healthsecurity performance scores derived from the D-CRITIC-CoCoSo model. This analysis identifieddistinct performance clusters and assigned grades, showing the distribution of countries acrossincome levels in both years
