  Fig. 4. (A) CiteSpace network analysis of collaboration among institutions involved in ICD application for HCM, 2000–2025. Each node, color-coded chronologically, represents an institution, and the size of the node corresponds to the relative volume of its research output. The different colors of the node rings indicate publication years (see the timeline color key at the bottom left). (B) Overlay visualization of the co-authorship analysis conducted using VOSviewer for institutions involved in ICD application for HCM, 2000–2025. In the map, a minimum occurrence threshold of 7 and a minimum citation count of 0 were set for institutions. Different nodes represent distinct institutions. Institutions with similar color tones share related research focuses, and the lines connecting nodes represent collaborative relationships between them
