* Estimated Number of Cases: Since NEISS is a probability
sample, each injury case has a statistical weight. National estimates of
product-related injury incidents are derived by summing the statistical
weights for the appropriate injury cases.
* CV (Coefficient of Variation): The CV, the standard error of the estimate divided by the estimate, is a measure of sampling variability (errors that occur by chance because observations are made only on a population sample).
* Number of Cases: This is the actual number of injury cases collected from the hospitals sampled. Since injury cases have different statistical weights, these “raw” numbers should not be used for comparative purposes.
* Product-Related Injuries: These are national estimates of the number of persons treated in U.S. hospital emergency departments with consumer product-related injuries during the given time period. The data system allows for reporting of up to two products for each person’s injury. Therefore, a person’s injury may be counted in two product groups.
