  1. Each multiple regression comprised 17 potential covariates, but only diet-related ones were retained by variable selection procedures. Coefficient estimates and significance (p-values) are shown, together with overall model significance and R-squared, for the regressions restricted to the selected diet-related covariates.
  2. *Test statistic of a null hypothesis that a covariate’s coefficient is equal to zero.
