What is an example of an incidence rate?
For example, if one hundred sow farms were followed for a year, and during this time 10 sow farms broke with a disease, then the incidence risk for that disease was 0.1 or 10%. In other words, a sow farm has a 10% chance of breaking in a year.
How do you find an incidence rate?
Definition. Number of new disease cases per population at risk. High Incidence implies high disease occurrence. Low Incidence implies low disease occurrence.
What's a high incidence rate?
That is, a rate ratio of 1.0 indicates equal rates in the two groups, a rate ratio greater than 1.0 indicates an increased risk for the group in the numerator, and a rate ratio less than 1.0 indicates a decreased risk for the group in the numerator.
