p_value	None
protocol	Prospective longitudinal cohort study using food frequency questionnaires at baseline (1993-1996) and 10-year follow-up (2003-2008), with Medicare claims linkage for ADRD identification. Three a prior

experiment_type	clinical
success_criteria	Statistically significant associations between dietary indices and ADRD risk in Cox regression models
expected_outcomes	Higher quality plant-based diets (higher PDI and hPDI) were expected to be associated with lower ADRD risk, while unhealthful plant-based diets (higher uPDI) were expected to increase risk
statistical_methods	Cox regression models
