Demographic characteristics, anthropometric measurements, and concentrations of biomarkers in patients with premature AMI and healthy controls.

*Values are mean±SD/median (IQR) except for gender which are presented as n(%).
**p value was obtained by comparing mean±SD values using Independent sample t test, however, Mann-Whitney U test was used to compare distributions for variables homocysteine, ferritin, sTfR and sTfR/ferritin.
BMI =  body mass index, sTfR =  soluble transferrin receptor.

* 除性别以例数（百分比，n(%)）形式呈现外，其余数据均以平均值±标准差（mean±SD）或中位数（四分位距Interquartile Range，IQR）表示。
** P值通过独立样本t检验对平均值±标准差数据进行比较获得；而同型半胱氨酸、铁蛋白、sTfR（soluble transferrin receptor）以及sTfR/铁蛋白这几个变量的分布比较则采用曼-惠特尼U检验。
BMI（body mass index，体重指数）；sTfR（soluble transferrin receptor，可溶性转铁蛋白受体）
