| 3. MEG Severity‐Adjusted | 1.240 | 1.074 | 1.163 |
| 4. MEG Not Severity‐Adjusted | 1.240 | 1.071 | 1.164 |
| 5. ETG Annual Episodes (Not Severity‐Adjusted) | 1.250 | 1.098 | 1.146 |
| 6. ETG—Episodes by MPC Class | 1.250 | 1.077 | 1.165 |
| Encounter | |||
| 7. Primary Diagnosis—CCS Disease Categories | 1.224 | 1.028 | 1.178 |
| Person—Regression Analysis | |||
| 8. ETG Severity‐Adjusted | 1.233 | 1.091 | 1.131 |

The regression‐based approaches of 8 and 9 apply log linear regressions. The expenditures allocated to the intercept are considered unallocated and are excluded from the analysis.
