    Statistik in Theorie und Praxis

    No full text
    Das Buch bringt eine Kombination aus mathematischer Theorie, einer Einführung in die Programmiersprache R und Berichten über real abgelaufene Statistikprojekte. Bei relativ niedrig angesetzten Eingangsvoraussetzungen bringt es so einen reichhaltigen Überblick über deskriptive Verfahren und über die klassische Teststatistik. Das Buch richtet sich primär an (zukünftige) Lehrkräfte der Mathematik, ist aber generell für einführende Lehrveranstaltungen der mathematischen Statistik geeignet

    Best Practices in Treatment of Laryngopharyngeal Reflux Disease: A Multidisciplinary Modified Delphi Study

    No full text
    Background Laryngopharyngeal reflux (LPR) is a common otolaryngologic diagnosis. Treatment of presumed LPR remains challenging, and limited frameworks exist to guide treatment. Methods Using RAND/University of California, Los Angeles (UCLA) Appropriateness Methods, a modified Delphi approach identified consensus statements to guide LPR treatment. Experts independently and blindly scored proposed statements on importance, scientific acceptability, usability, and feasibility in a four-round iterative process. Accepted measures reached scores with >= 80% agreement in the 7-9 range (on a 9-point Likert scale) across all four categories. Results Fifteen experts rated 36 proposed initial statements. In round one, 10 (27.8%) statements were rated as valid. In round two, 8 statements were modified based on panel suggestions, and experts subsequently rated 5 of these statements as valid. Round three's discussion refined statements not yet accepted, and in round four, additional voting identified 2 additional statements as valid. In total, 17 (47.2%) best practice statements reached consensus, touching on topics as varied as role of empiric treatment, medication use, lifestyle modifications, and indications for laryngoscopy. Conclusion Using a well-tested methodology, best practice statements in the treatment of LPR were identified. The statements serve to guide physicians on LPR treatment considerations
