In infants 1-3 years of age, we found higher serum ferritin values associated with higher cognitive function, as measured by the Mullen Scales of Early Learning (P = .02 for the nonlinear relationship). A serum ferritin of 17 μg/L corresponded to the maximum level of cognition, beyond which there was no meaningful improvement. TRIAL REGISTRATION: Clinicaltrials.gov NCT01481766 and NCT01869530.
在 1-3 岁的婴儿中，我们发现较高的血清铁蛋白值与较高的认知功能相关，这是通过 Mullen 早期学习量表来衡量的（非线性关系的 P 值为.02）。血清铁蛋白为 17μg/L 时，认知水平达到最高，之后再无显著改善。临床试验注册：Clinicaltrials.gov NCT01481766 和 NCT01869530。
