The relationship between serum iron and interleukin-6 levels in all subjects.

(Dependent variable: serum iron concentration).
*P<0.05 and **P<0.001, general linear model. AMI, acute myocardial infarction; IL-6, interleukin 6; SE, standardized error. The intercept is the predicted value of serum iron concentration in AMI group. The predicted value is 71.872 µg/dl. The serum iron concentration in the control group was, on average, 35.494 µg/dl higher than that in the AMI group. For every one unit increase in IL-6 concentration, there was a decrease of 0.625 units in serum iron concentration.

(因变量：血清铁浓度)。*P<0.05 及 **P<0.001，采用一般线性模型。急性心肌梗死（acute myocardial infarction, AMI）；白细胞介素6（interleukin 6, IL-6）；标准化标准误（standardized error, SE）。截距为急性心肌梗死组的血清铁浓度预测值，该预测值为71.872 µg/dl。对照组血清铁浓度平均值较急性心肌梗死组高35.494 µg/dl。白细胞介素6浓度每升高1个单位，血清铁浓度即降低0.625个单位。
