CiteSpace-generated circular thematic landscapes identified high-confidence clusters (Figure 2C): Cluster #0 (“cerebrospinal fluid,” “N-glycan profile,” silhouette coefficient: 0.726) emphasized glycomic analysis of AD clinical samples; Cluster #1 (“neurodegenerative diseases,” silhouette coefficient: 0.712) contextualized N-glycosylation within broader neurodegeneration; and Cluster #3 (“GNT-III activity,” silhouette coefficient: 0.909) focused on enzymatic regulation of glycan maturation. The gene discussed is MGAT3; the disease is Alzheimer disease.
