Charts 13-28 are the result of using discharge data that has been severity adjusted to try to eliminate the issue of different degrees of illness in different hospitals. The charts use the confidence interval technique to answer the question of significance. If the vertical bar of confidence interval for each hospital peer group overlaps the blue confidence interval bars for the state mean then there is not a significant difference between the two.
