^BCook et al used original dataset to define waist circumference cut-point

^CCruz et al originally used unpublished data which has since been published. The published data has been used in the current manuscript.(17)

^DCook et al originally used fasting glucose ≥110 mg/dl to define Impaired Fasting Glucose. The criteria for Impaired Fasting Glucose has been updated by the American Diabetes Association as a fasting glucose ≥100 mg/d.(16) The revised cut-point has been used.

^EAll three variations for defining elevated blood pressure have been updated.(14)
