This calculator is designed for healthcare professionals to determine the Number Needed to Treat (NNT), which indicates how many patients need to be treated to prevent one additional negative outcome. It helps in assessing the effectiveness of a healthcare intervention.
All calculations are based on statistical methods for NNT calculation as described in the scientific literature.
\( \text{NNT} = \frac{1}{\text{Control Risk} - \text{Experimental Risk}} \)
Number Needed to Treat (NNT) is a statistical measure that indicates how many patients need to be treated in order to prevent one additional bad outcome.
NNT is useful for determining the effectiveness of a healthcare intervention and comparing different treatments.
No, NNT is always a positive number. It represents the number of patients needed to treat to prevent one adverse outcome.
NNT does not account for variations in patient populations and may not apply universally across different settings.
An ideal NNT value is as low as possible, indicating that fewer patients need to be treated to achieve a benefit.
