| OR | 95% CI | P value | |
| Baseline GCSI Score higher than 2.6 | 3.23 | (1.06 to 9.9) | 0.04 |
| Gastric retention >20% at 4 hours before G-POEM | 3.65 | (1.14 to 11.66) | 0.029 |
Note: the following variables were tested in the model: upper abdominal pain before G-POEM, baseline GCSI Score higher than 2.6, baseline nausea/vomiting, baseline Fullness/early satiety, baseline bloating score and gastric retention >20% at 4 hours before G-POEM.
