How to interpret odds ratio greater than 2
WebFor odds ratio the value is calculated by dividing the probability of success by the probability of failure. Hence taking a variable X as probability of success and equating it with 0.9723952 will give you a sucess ratio of 0.49 or an odds of 97.2 to 100 for the sucess of the event.
