1
Values are median (range) for continuous variables and n (%) for categoric variables, unless otherwise indicated. DI, dietary index.
2
P values for trend were calculated using a linear model for continuous variables and the chi-square test for categoric variables.
3
Time between the first dietary assessment and the outcome assessment.
