Data presented were averaged (year 0/7), except education (maximum attained over follow-up) and cellular adhesion molecules (as marked). N=3818 for all non CAM variables.
Tests for trend of continuous variables were based on general linear regression with averaged year 0/7 dietary pattern as continuous independent variable adjusted for race sex center and age. Chi-square tests were used for categorical variables across all 5 levels of dietary pattern variables.
3 Trend across A Priori Diet Quality Score significant at <0.05 for all variables except VCAM year 7 (p-value 0.29)
Meat dietary pattern diet and FV dietary pattern are principal components, centered on zero with a standard deviation of 1.0.
Trend FV dietary pattern significant at <0.05 for all variables except VCAM year 7 (p-value 0.48) and VCAM year 15 (p-value 0.64)
Trends across Meat dietary pattern significant at <0.05 for all variables except waist (p-value 0.99), VCAM year 7 (p-value 0.35) and VCAM year 15 (p-value 0.15)
