What Does An Odds Ratio Of 1 Mean? If an odds ratio (OR) is 1, it means there is no association between the exposure and outcome. So, if the 95% confidence interval for an OR includes 1, it means the results are not statistically significant. What does a odds ratio of 0 mean? Odds-ratio The
How Do You Calculate Rate In Epidemiology? Reporting: To report a risk or rate “per m,” simply multiply it by m. For example, an incidence proportion of 0.0010 = 0.0010 × 10,000 = 10 per 10,000. How do you calculate rate of disease? The denominator is the sum of the time each person was observed,
