Evidence-Based Practice / Unit 6 EBP 0831 short lesson, about 20 seconds
Risk Difference
Captions available
The idea
The risk difference is one group's absolute risk subtracted from the other's — the absolute difference between them.
In practice
Three in a hundred against two in a hundred, a difference of one in a hundred.
Where people slip
The risk difference is stated in the same units as the risks themselves. That is what makes it readable.
