Statistical approaches to relationships between sitting height and leg length in adults

Background: Relationships between sitting height (SH) and leg length (LL) in adults are almost always studied in terms of ratios such as the Cormic Index (CI), SH/stature, rather than as primary variables. They are affected by genetics and childhood nutrition. Aim: To characterize these relationships and test whether the CI is ideal as an index of relative LL. Subjects and methods: Regression and reduced major axis (RMA) equations were...
