^aReference value is exercise ≤1 times per week, ^bAge divided by 10, ^cHDL had female n = 41, female obs = 77, male n = 77, male obs = 138, ^dCRP had female n = 42, female obs = 77, male n = 77, male obs = 138. The CRP values was log transformed at analysis, ^eSystolic BP had female n = 43, female obs = 78, male n = 78, male obs = 141
HDL = high density lipoprotein; CRP = C-reactive protein; BP = blood pressure
