Das Hazard Ratio ist ein Quotient aus den Hazards von zwei Gruppen und gibt an, um wie viel die Sterberate in der einen Gruppe höher ist im Vergleich zu der Sterberate der anderen Gruppe. Das... Die Hazard Ratio (oder Hazard Rate) entspricht dem Verhältnis der Hazard Raten zweier Gruppen. Die Hazard Ratio (HR) wird häufig bei klinischen Studien verwendet. Sie gibt das Risikoverhältnis zwischen verschiedenen Behandlungsgruppen an. Dabei wird das Risiko einer Behandlungsgruppe zum Risiko einer 2. Gruppe in Relation gesetzt. Als Beispiel: Bei einer klinischen Studie werden die Abheilungsraten einer Erkrankung erfasst. Während in der Kontrollgruppe II 50% der Patienten abheilen Das Hazard Ratio als deskriptives Maß für den Unter-schied von Überlebenszeiten wird erläutert. Schlussfolgerungen: Wenn nicht spezielle Verfahren bei der Analyse von Überlebenszeitdaten eingesetzt oder de-ren Annahmen nicht überprüft werden, können die Ergeb-nisse fehlerhaft sein. Der Leser einer wissenschaftlichen Publikation sollte diese Fallstricke kennen und beurteilen können, ob In survival analysis, the hazard ratio (HR) is the ratio of the hazard rates corresponding to the conditions described by two levels of an explanatory variable. For example, in a drug study, the treated population may die at twice the rate per unit time of the control population. The hazard ratio would be 2, indicating higher hazard of death from the treatment. d Hazard Ratio. The hazard ratio is the ratio of (chance of an event occurring in the treatment arm)/ (chance of an event occurring in the control arm) (20 ). The HR has also been defined as, the ratio of (risk of outcome in one group)/ (risk of outcome in another group), occurring at a given interval of time ( 21 ). Hazard ratio (HR) is a measure of an effect of an intervention on an outcome of interest over time. Hazard ratio is reported most commonly in time-to-event analysis or survival analysis (i.e. when we are interested in knowing how long it takes for a particular event/outcome to occur).
