The number needed to treat (NNT) is an epidemiological measure used in communicating the effectiveness of a health-care intervention, typically a treatment with medication. The NNT is the average number of patients who need to be treated to prevent one additional bad outcome (e.g. the number of patients that need to be treated for one of them to benefit compared with a control in a clinical trial). It is defined as the inverse of th Die Anzahl der notwendigen Behandlungen (englisch number needed to treat, kurz: NNT) ist eine statistische Maßzahl, die angibt, wie viele Patienten pro Zeiteinheit (z. B. 1 Jahr) mit der Testsubstanz oder Testmethode behandelt werden müssen, um bei der untersuchten Population das gewünschte Therapieziel zu erreichen (z. B. die Anzahl der Herzinfarkte um 10 % zu reduzieren) Definition. The Number Needed to Treat (NNT) is the number of patients you need to treat to prevent one additional bad outcome (death, stroke, etc.). For example, if a drug has an NNT of 5, it means you have to treat 5 people with the drug to prevent one additional bad outcome. More detailed discussion of the nature of the NNT measure can be found. Die NNT ist ein Effektstärkemaß, welches zur Bewertung einer Therapie im Vergleich zu einer Kontrolle hinsichtlich des Auftretens eines unerwünschten Ereignisses herangezogen wird. Die NNT ist der Kehrwert der absoluten Risikoreduktion: NNT = 1/ AR ** Benefits of numbers needed to treat NNTs can be used either for summarising the results of a therapeutic trial or for medical decision-making about an**...

- Number Needed to Treat (NNT) represents the number of patients over a given time period that one would need to treat to achieve one additional study endpoint. As an example, in the PROSEVA trial of patients with severe ARDS , prone positioning decreased 28-day all-cause mortality compared to supine positioning (16% vs. 32.8%) with a NNT of 6
- It is a simple statistical concept called the Number-Needed-to-Treat, or for short the 'NNT'. The NNT offers a measurement of the impact of a medicine or therapy by estimating the number of patients that need to be treated in order to have an impact on one person. The concept is statistical, but intuitive, for we know that not everyone is helped by a medicine or intervention — some benefit, some are harmed, and some are unaffected. The NNT tells us how many of each

In this article we discuss the concept and limitations of this measure Topics: Number.

The number needed to treat (NNT) is a useful way for clinicans to describe the benefit or harm of a treatment as well as the costs involved. When interpreting the NNT it is essential to use the NNT in a clinically equivalent and appropriate setting. When evaluating the consequences of a treatment clinicians should make sure that the patients being treated have the same risk profile asthe study. The number needed to treat (NNT) is a valuable information in treatment decisions. This is the result of a calculation based on published data, collected from an intervention study. NNT is the inverse of the absolute risk reduction (1/ARR) between two treatment options. It is always expressed by a value rounded up to whole numbers, between 1 and infinity, depending on the effectiveness of the.

Number needed to treat. NNT represents the number of patients who would need to be treated with a specified intervention in order to obtain one additional positive outcome that would not have occurred had the patient received the comparison treatment. Alternatively, it is the number of patients who would need to be treated in order to prevent. That number exists, and it's called the number needed to treat. Developed by a trio of epidemiologists back in the '80s, the NNT describes how many people would need to take a drug for one. Critical Appraisal: Appraising a Treatment, Early Goal Directed Therapy Analysis: Number Needed to Treat Number Needed to Treat Lesson Progress 0% Complete The Number Needed to Treat is a useful concept. It is the inverse of the absolute risk reduction. It means, in very simple terms how many times would I have to apply the [ Number Needed to Treat (NNT) tells clinicians how many people you have to treat to prevent a bad outcome. The formula for number needed to treat is (1/ARR). As the absolute risk reduction increases, the number needed to treat will decrease, meaning that the treatment is more efficacious. Clinicians ultimately want number needed to treat to be LOW, meaning that few people need to be treated to.
