Fig. 2

A ferroptosis-based VOSviewer-generated map. Visualization is based on bibliographic data from all publications related to ferroptosis, retrieved from the Web of Science using the Science Citation Index Expanded (SCI-EXPANDED) database [38]. The map presents a co-occurrence analysis using fractional counting as the counting method, based on author keywords. To improve the visibility of co-occurrence patterns, some obvious ferroptosis-related keywords like “ferroptosis,” “lipid peroxidation,” “cell death,” and “GPX4” were excluded from the map. A complete table containing all keywords is available in SI part 2—Table S3
