Table 3. Risk of premature AMI in Pakistani adults with quartiles of ratio of sTfR to ferritin.
| Q1 | Q2 | Q3 | Q45 | p value for trend | |
| Crude 1 | 4.01(2.11–7.61)** | 2.70(1.40–5.12)** | 1.20(0.64–2.25) | 1 | <0.01 |
| Adjusted 2 | 3.29(1.54–7.03)** | 3.08(1.38–6.89)** | 1.21(0.57–2.57) | 1 | <0.01 |
| Adjusted 3 | 3.26(1.52–7.00)** | 3.10(1.39–6.94)** | 1.21(0.57–2.57) | 1 | 0.912 |
| Adjusted 4 | 2.47(1.29–8.16)* | 3.24(1.29–8.16)* | 1.11(0.46–2.69) | 1 | 0.027 |
1
Values are matched OR (95% CI) from conditional logistic regression.
2
Values are matched OR (95% CI) from conditional logistic regression adjusted for vitamin B12 and HDL-cholesterol.
3
Value are matched OR(95%CI) from conditional logistic regression adjusted for vitamin B12, HDL-cholesterol and blood Pb.
4
Values 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.
5
Considering 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 <0.05.
**
p value<0.001.
