Evidence-Based Practice / Unit 6 EBP 0835 short lesson, about 20 seconds
Reading Which Way a Ratio Points
Captions available
The idea
If the outcome is wanted, a relative risk above one means the intervention did better. If the outcome is unwanted, above one means it did worse.
In practice
A ratio above one for an undesirable outcome: the condition is the worse one.
Where people slip
The same number means opposite things depending on whether the outcome is good. Check the outcome before reading the ratio.
