Rate is the number of new cases that occur per the total amount of time a person is at risk of becoming a case. It is expressed as person-time such as 17.8 cases per 100 person years. Odds is the likelihood of a new case occurring rather than not occurring.

How to calculate the odds?

To convert from a probability to odds, divide the probability by one minus that probability. So if the probability is 10% or 0.10 , then the odds are 0.1/0.9 or '1 to 9' or 0.111. To convert from odds to a probability, divide the odds by one plus the odds.

How do you Analyse odds ratio?

In a 2-by-2 table with cells a, b, c, and d (see figure), the odds ratio is odds of the event in the exposure group (a/b) divided by the odds of the event in the control or non-exposure group (c/d). Thus the odds ratio is (a/b) / (c/d) which simplifies to ad/bc.
