Term used in statistics as a benchmark in clinical trials. NNT indicates the number of patients to be treated to prevent a specific event (endpoint). Calculation: NNT = 100: (absolute difference between treatment arms). The lower the NNT the more "effective" the treatment (very popular and often used for guidelines; but does not indicate when the gain - e.g. prevention of a death - occurs).
