1 ID: Anonymous hospital identifier;
2 LB_B: Lower bound of the Bonferroni confidence interval;
3 LB_95: Lower bound of the 95% confidence interval;
4 D: departure of a hospital's CSR compared with the national CSR/national trend;
5 UB_95: Upper bound of the 95% confidence interval;
6 UB_B: Upper bound of the Bonferroni confidence interval;
7 CI_95: +: a 95% CI suggests a significantly higher hospital's rate/trend compared with the national rate/trend,
-: a 95% CI suggests a significantly lower hospital's rate/trend compared with the national rate/trend,
NS: a 95% CI does not suggest a significant departure of the hospital's rate/trend compared with the national rate/trend.
8 CI_B: +: a Bonferroni-corrected CI strongly suggests a significantly higher hospital's rate/trend compared with the national rate/trend,
-: a Bonferroni-corrected CI strongly suggests a significantly lower hospital's rate/trend compared with the national rate/trend,
NS: a Bonferroni-corrected CI does not suggest a significant departure of the hospital's rate/trend compared with the national rate/trend.
9 P value: Probability of observing departures such as these assuming the null hypothesis of no departure is true.
10IP: Interpretation: EA: External audit and general measures recommended; GM: General measures recommended.
