Hematological parameters of adult rats treated with control and restricted-iron (ARI) or enriched-iron (AEI) diets and of young rats.

Average and standard deviation: n = 7 (CT); n = 5 (ARI); n = 8 (AEI); n = 6 (young). Difference between the control group and test groups:
*p≤0.05;
**p≤0.01;
***p≤0.001 (Student's t-test).

均值与标准差：CT组n=7，ARI组n=5，AEI组n=8，青年组n=6。对照组与实验组的组间差异显著性标记为：*p≤0.05；**p≤0.01；***p≤0.001，统计方法采用学生t检验（Student's t-test）。
