[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.

[Clinical research in service of clinical medicine: Contexts, practice, methodology and theory of Paul Martinís "clinical proof" - part 3: Causally relevant elements of Martini's clinical proof and epistemological remarks].

In the third part of our quadripartite series on Paul Martini and his concept of clinical proof we shortly present the mostly procedural elements of his test of treatment. We discuss their causal conduciveness: what do they contribute to infer causality from effect? Finally we comment on some of Martini's epistemological assumptions and methodological decisions that underpin his method of proof.

[Clinical research in service of clinical medicine: Contexts, practice, methodology and theory of Paul Martini's "clinical proof" - part 2: Martini's early therapeutic research].

This article aims to examine Paul Martini's early therapeutic research. It traces the development and early practice of his methodology by focussing on four clinical studies which Martini conducted in the years 1928 to 1932. The studies show a methodological transition from uncontrolled drug evaluation to systematic method-based drug testing and the production of increasingly valid results.

[Clinical research in service of clinical medicine: Contexts, practice, methodolody, and theory of Paul Marini's "clinical proof" - part 1].

This is the first contribution to a quadripartite series on Paul Martini, internist and early clinical epidemiologist (1889-1964), and his clinical proof ("klinischer Beweis"). Following a historical introduction and the presentation of our programme, the text deals with Martini as a person and his socio-cultural background between the end of the Great War and the 1960s. It throws light on his original, innovative and risky research programme, and outlines various factors which led Martini to his central life issue: the therapeutic-clinical proof based on controlled investigations.

[Inflammatory Bowel Diseases: Regional Deprivation, Disease Characteristics and Relevant Health Care].

Hintergrund: Regionale Deprivation ist als ökologischer Parameter eine Komponente der sozialen Determinanten von Gesundheit. Zu ihrer Messung stehen in Deutschland der "German Index of Multiple Deprivation" (GIMD) und der "German Index of Socioeconomic Deprivation" (GISD) zur Verfügung. Chronisch entzündliche Darmerkrankungen (CED) sind keine häufigen, aber ernste körperliche Erkrankungen unklarer Ätiologie, mit vergleichsweise frühem Auftreten im Erwachsenenalter, oft chronisch-behandlungsbedürftigem Verlauf und unsicherer Prognose.
