What is the relationship between adherence to dietary guidelines/recommendations or specific dietary patterns, assessed using reduced rank regression analysis, and cardiovascular disease?
ConclusionInsufficient evidence, due to a small number of studies, was available to examine the relationship between dietary patterns derived using reduced rank regression and risk of cardiovascular disease. The disparate nature of the methods used made it difficult to compare results, and therefore, no conclusions were drawn.
GradeIV – Not Assignable
- Four positive quality prospective cohort studies that used reduced rank regression to examine the relationship between dietary patterns and cardiovascular disease (CVD) status were included in this review. Comparison across studies is limited by the small number of studies, differences in methodologies used, and in the populations studied. Therefore no conclusions were drawn.
- More U.S. population-based research is needed to examine dietary patterns and risk of cardiovascular disease using reduced rank regression, preferably with more consistent methods and response variables.

More research using reduced rank regression should be conducted. Additionally, standardization in methodology, such as food groupings and response variables used, are also needed.
