Standardized Mortality Ratio
The Standardized Mortality Ratio (SMR) is the ratio of observed to the expected number of deaths in the study population under the assumption that the mortality rates for the study population are the same as those for the general population. For nonfatal conditions, the Standardized Mortality Ratio is sometimes known as the Standardized Morbidity Ratio. Entering observed and expected number of cases (deaths) will result in the point estimate of SMR and the confidence intervals at the user's setting.
