The Simplified GDQS was generated by condensing the second and third consumption amount categories in Table 3 for all food groups (except red meat, for which trichotomous scoring was retained to allow for healthy scoring at higher intake amounts, as in the GDQS). Refer to footnote to Figure 1 for derivation of the continuous energy-adjusted overall nutrient adequacy variable. P for difference (P, diff) is estimated from using Wolfe's tests comparing metric-outcome correlation coefficients between the GDQS and either the Simplified GDQS or PDQS-like Metric (34). *P < 0.05 correlations and Wolfe's tests.
