Abstrakt: |
The magnitude of treatment effect from randomized controlled trials can be measured in various ways. The number needed to treat is a recently described measure that has been shown to offer several advantages in the clinical interpretation and application of reported treatment effects. It quantifies the number of patents that must be treated in order to prevent one patient from developing the specified outcome. The methods necessary to calculate traditional measures of treatment effect, as well as the number needed to treat, are outlined using the management of diabetic retinopathy as an example. The uses and limitations of the number needed to treat are also discussed. |
