| success_criteria | Statistically significant associations between dietary change categories and ADRD risk |
| sample_size | 45065 |
| statistical_methods | Cox regression models with dietary change categorization |
| p_value | None |
| effect_size | HR 1.25 for large uPDI increase, HR 0.89 for large uPDI decrease vs stable |
