*P < 0.01 in estimate between males and females. F, female; M, male; LN, LN-transformed values.
Obtained from a model in Mx without correction for age.
Beta for the regression of metabolic syndrome traits on age. The effect of age was significant for all traits (P < 0.001, for dropping β age in both sexes).
For height only, the β in this column represents the effect of birth year rather than age.
Corrected for medication use.
