The top number in each cell is the change in the sample average number of encounters from 2004–2006 and the bottom is the standard deviation.

The top number in each cell is the difference between the TexKat change and the change for that control group, while the bottom number is the p-value from a t-test of the equivalence of the TexKat change and the change for that control group.
