Chi-square analysis comparing the proportionof patients with success versus those with failure after PJI treatment according to the Delphi-based consensus method [8] and MSIS ORT [11]
| Procedure type | Delphi | MSISa | |

| Success, % (n) | 70 (71) | 55 (63) | |
| Failure, % (n) | 30 (31) | 45 (51) | |

| Hip procedures | |||
| Success, % (n) | 74 (29) | 55 (26) | |
| Failure, % (n) | 26 (10) | 45 (21) | |

| Knee procedures | |||
| Success, % (n) | 67 (42) | 55 (37) | |

a
According to the MSIS, “failure” is defined as treatment failure that is directly or indirectly related to PJI (Tiers 3B, 3C, 3D, 3E, 3F, and 4A).
