Variables were included in the multivariate analysis if the univariate P-vale< 0.2; Therefore, BMI, Education, Systolic blood pressure, CABG, CVA, IHD, Severe anemia, Hemoglobin and Creatinine level were excluded from the multivariate analysis
^aSub-distributional hazard ratio
^bCoronary artery bypass graft
^cCardiovascular accident
^dIschemic heart disease
^eSevere anemia was defined as Hb < 8 based on WHO criteria
