Health and biomedical research are undergoing rapid advancement. New therapies, digital tools, and data-driven methods emerge on a daily basis, often accompanied by audacious claims and rapid shifts in attention. For readers lacking expertise in specialized fields, this wealth of information can prove both exhilarating and daunting: What is truly changing? Which topics are gaining momentum, and which are losing traction? Where are the gaps that still prevent scientific knowledge from becoming real-world solutions?

This book provides a lucid and empirically substantiated approach to these inquiries. Instead of emphasizing a particular discipline, it employs "scientometrics"-the quantitative study of scientific literature-to trace the evolution of research domains over time. By examining publication trends, citation patterns, collaboration networks, and thematic clusters, scientometric analyses can reveal the structure of knowledge: the communities that shape a topic, the concepts that connect disciplines, and the emerging themes that signal future directions. It is imperative to acknowledge that these maps do not supersede the necessity for clinical trials, laboratory experiments, or public health evaluations. Rather, they serve as a supplementary resource, offering a comprehensive overview of the manner in which evidence is generated, structured, and disseminated within the scientific ecosystem.
