Risk of premature AMI in Pakistani adults with quartiles of ratio of sTfR to ferritin.

1Values are matched OR (95% CI) from conditional logistic regression.2Values are matched OR (95% CI) from conditional logistic regression adjusted for vitamin B12 and HDL-cholesterol.3Value are matched OR(95%CI) from conditional logistic regression adjusted for vitamin B12, HDL-cholesterol and blood Pb.4Values are matched OR (95% CI) from conditional logistic regression after adjusting for blood Pb, vitamin B12, HDL-cholesterol and fasting serum glucose levels >126 mg/dL.5Considering the hypothesis that risk of premature AMI would be more at low ratio of sTfR to ferritin, the quartile indicating the highest ratio was taken as reference.*p value **p value
