DGAI-2010, 2010 Dietary Guidelines Adherence Index.
1
Quintile category means (95% CI) derived with general linear models adjusted for age (continuous), sex, body mass index, mean arterial pressure, heart rate, and smoking.
2
Derived from general estimating equations with DGAI-2010 entered as a continuous score.
