Appendix 6.
Results comparisons between the propensity score method-based sensitivity analysis and multivariable logistic regressions with main effects only Based on the matched sample, the effect of SA on outcomes was tested for significance using the Cochran-Mantel-Haenszel test. Common odds ratio (COR) Bonferroni corrected 95% confidence intervals and p-values are reported.

| Length of Stay > 75th percentile | 1.18 (1.13, 1.23) | 1.16 (1.12, 1.20) |
| Utilization of economic resources > 75th percentile | 1.13 (1.11, 1.22) | 1.13 (1.09, 1.18) |
a
All 95% CIs and the associated p-values were both Bonferroni corrected for multiple comparisons
b
All corrected p-values were <0.0001 except for mortality (p>0.99).
c
All corrected p-values were <0.0001 except for mortality (p=0.43).
