[Clinical research in service of clinical medicine: Contexts, practice, methodology and theory of Paul Martini's "clinical proof" - part 4: Adoption, resonance, and a résumé].

Having dealt with Martini's understanding of causality and his procedural elements of evidence in the third part, the concluding article once again takes a historical perspective. It (1) traces the positionings and contexts of Martini's methodology in a sort of historical longitudinal section and (2) discusses the reasons for the rather reluctant response to his research programme in German and international medicine. We then focus (3) on Martini's understanding and concept of clinical research, the specific challenges he faced in post-war German medicine - and what remains of it today. Finally, we summarise the key findings of our article series and reflect on Martini's work in terms of its special nature and significance for clinical medicine in the 20 century.
