Evidence-Based Practice / Unit 6 EBP 0843 short lesson, about 20 seconds
Reading a Number Needed to Treat
Captions available
The idea
Whether a number needed to treat is acceptable depends on what the intervention costs, how burdensome it is, and how serious the outcome is.
In practice
Thirteen people using an inexpensive, low-burden aid so that one more person benefits.
Where people slip
There is no threshold. Thirteen is excellent for a cheap, safe intervention and poor for an expensive, invasive one.
