Associations between adherence to the dietary patterns and incident dementia in the total sample
| Dietary patterns | Model 1a | p value | Model 2a | p value | ||||
|---|---|---|---|---|---|---|---|---|
| Dementia n = 125/602b | Dementia n = 121/573b | |||||||
| HR | 95% CI | HR | 95% CI | |||||
| Healthy (factor 1) | 0.87 | 0.75; 1.02 | 0.08 | 0.83 | 0.67; 1.03 | 0.09 | ||

HR and 95% CI estimated using a Cox proportional hazards model with follow-up time (years) as the time scale
aModel 1 is adjusted for sex and birth year. Model 2 is adjusted for sex, birth year, BMI, energy intake, serum cholesterol level, hypertension, diabetes, physical activity level, educational level, and smoking status
bDementia events/total cases. Those with missing data were excluded in model 2 (n = 29 with missing data, n = 5 for BMI, n = 3 for serum cholesterol, n=5 for education, n = 10 for physical activity level and n = 7 for smoking)
