^a CRP, C-reactive protein; HomaRes, insulin resistance;VLDL, very low densitity lipoprotein; Aasi, vessel stifness; WH, waist-hip ratio; BNP, B-type or brain natriuretic peptide; BMI, body mass index; Apo, apolipoprotein; Supar, soluble urokinase activator receptor.

^b Entropy for the full model as defined in the MPlus programme (1 - standard entropy) for the error structure. Changes signifies deviation from the model without covariates.

^c Ultrasound recording of systolic and diatolic blood pressure: UL4, left and rigth measurements are seperate indicators;

UL2, average of left and right systelic and diastolic blood pressure, respectively, are used as indicators

^d Fraction of traits in all classes normalized by the LCA-SEM partition. Only the traits listed and the mode of blood pressure measurements are included in the calculation

^e Fraction of indicators not correalted after LCA-SEM partition
