Variances are on the leading diagonal, covariances are below the diagonal, and correlations are above the diagonal. Variables are: blWC, Blom transformation of waist circumference; trFG, 100 x natural log of fasting plasma glucose; trTG, 100 x natural log of fasting plasma triglycerides; HDL, fasting plasma HDL; DBP, diastolic blood pressure. Numbers at the end of the variable name indicate twin 1 or twin 2.
