Outcome Measures
Primary Outcomes (2)
Average Nutritional Knowledge Score (NK)
Studies often show average scores around 50-60% of correct answers. Knowledge is often measured as a percentage of a total possible score, with a 75% threshold sometimes used to define "basic" or "good" knowledge.
through study completion, an average of 1 year
Mediterranean Diet Adherence (AMD) value
High Mediterranean Diet Adherence (AMD) is strongly linked to a reduced risk of developing and progressing to advanced Age-Related Macular Degeneration (AMD), with studies showing 34% to 60% lower risk compared to low adherence. A diet rich in vegetables, fruits, and nuts significantly lowers this risk.
