A confidence interval for the standardized mortality rate ratio (SMRR) provides a range of values within which the true SMRR is likely to fall, given a specified level of confidence (commonly 95%). It is calculated using the point estimate of the SMRR and its standard error, typically derived from the observed deaths and person-time at risk. If the confidence interval does not include 1, it suggests a statistically significant difference in mortality rates between the groups being compared. This interval helps to assess the reliability and precision of the SMRR estimate in epidemiological studies.
