Blurring boundaries or structural coupling? Revisiting the science-medicine interface through the analogy of politics and law.
Article in Frontiers in sociology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Recent developments in cutting-edge medicine have inspired numerous analyses claiming the boundaries between scientific research and medical practice are blurring. This paper offers an alternative description of the dynamics at stake. Drawing on Luhmann's systems theory, it analyzes the relationship between medicine and biomedical science as a historically evolved pattern of structural coupling between two operationally closed functional systems. Methodologically, it employs systems comparison, using the well-developed systems theoretical description of the law-politics relationship as a template for examining analogies to the relation between medicine and science. Through a reconstruction of their center/periphery-differentiation, contingency formulae, structural coupling, and conditional programs, it shows that both constellations are marked by a distinctive arrangement of mutual externalization of legitimation. A historical account of the co-evolution of medicine and law further clarifies why medicine ultimately externalized the justification of its decision programs to science. Against this background, contemporary biomedical transformations are interpreted as signs of strain on established coupling mechanisms rather than as evidence of systemic fusion. The blurring boundaries debate thus appears as a symptom of intensified interdependence under conditions of scientific innovation to which the medical system is forced to react.
