Forest plot

Forest plot

Ein Forest plot ist eine graphische Darstellung der Ergebnisse einer Metaanalyse von mehreren biomedizinischen Studien. In der Regel ist das zahlenmäßige Ergebnis jeder Einzelstudie als Kästchen auf einer horizontalen Achse repräsentiert, zum Beispiel die durch eine Behandlung erreichte Besserungsrate in Prozent. Die Größe des Kästchens kann die Power (statistische Aussagekraft) der Studie anzeigen. Die Streubreite der Meßwerte (Varianz, Konfidenzintervall) kann durch eine horizontale Linie durch das Kästchen angedeutet werden. Es handelt sich also um einen modifizierten Boxplot.

Forest plots sind seit den 1970er Jahren üblich. Sie erlauben dem Leser der Metaanalyse eine schnelle visuelle Orientierung über gemeinsame Trends der analysierten Studien.

Der Name forest plot („Waldzeichnung“) soll auf die Vielzahl paralleler Linien abzielen, die entfernt an eine Baumgruppe erinnert [1]
