aAll logistic regressions were adjusted for age, country, and gender where appropriate. All ORs were significant (P<.001) with the exception of low HDL-C and awareness of SBP (P=.024).
bR2 shows the Nagelkerke R2 unique variance attributable to this variable after controlling for age, gender, and country where appropriate.
cHeart Age was calculated from different algorithms depending on available valid values of TC, HDL-C, and SBP.
