From: Research trajectory of the mechanism of preeclampsia: a scientometric perspective
(A) Author collaboration network: Node size indicates publication count, and node color reflects the research timeline (red = recent). Links represent collaboration strength. Prominent authors, such as Granger, Joey P, and Lamarca, Babette, focus on oxidative stress and angiogenic imbalance. Sub-networks highlight collaborations on placental dysfunction and immune dysregulation. (B) Co-citation network: Node size reflects citation frequency, and links represent co-citation relationships. Key authors like Roberts, JM, and Redman, CWG contributed foundational studies on placental ischemia and inflammatory mechanisms. The network shows strong interdisciplinary connections
