a
p-value for the interaction terms for time and RTEC; this value is an indicator of the statistical significance of whether cognitive trajectories by RTEC consumption category differ by period of observation
b
Adjusted for age, gender, education level, BMI, ever smoker, ever drinker, frequency of moderate physical activity per week, history of myocardial infarct, stroke, and diabetes, index of help needed with daily activities, marital status, time, time*time and interactions between time and RTEC frequency category.
