= actual number of ED visits; = estimated number of ED visits; L95% = lower 95% confidence interval of the estimate; U95% = upper 95% confidence interval of the estimate. Those categories comprising less than 1% of the variables as described in the appendix are excluded; thus, the percentage sum will not add up to 100.
