Definition of composite endoscopic and histological remission determined by selected endoscopic and histological scores
| Endoscopic/Histological scores | Endoscopic remission | Histological remission | Endo‐histological remission |
|---|---|---|---|
| MES/RHI | MES 0 | RHI ≤3 | MES 0‐RHI ≤ 3 |
| MES/NHI | MES 0 | NHI ≤1 | MES 0‐NHI ≤ 1 |
| UCEIS/RHI | UCEIS ≤1 | RHI ≤3 | UCEIS ≤1 ‐RHI ≤3 |
| UCEIS/NHI | UCEIS ≤1 | NHI ≤1 | UCEIS ≤ 1‐NHI ≤ 1 |
| PICaSSO/RHI | PICaSSO ≤3 | RHI ≤3 | PICaSSO ≤ 3‐RHI ≤3 |
| PICaSSO/NHI | PICaSSO ≤3 | NHI ≤1 | PICaSSO ≤ 3‐NHI ≤ 1 |
