Abstract
We read with interest the review by Kord-Varkaneh et al. which examined the effects of vitamin D supplementation on IGF-1 levels in humans. We believe that the article suffers from severe methodological faults and subsequently the conclusions are likely to be biased. Thus, the authors should address the mentioned limitations and update the analyses to provide robust and trustful estimates. We are concerned that without correction, the analyses may lead to erroneous findings and conclusions.
摘要
我们饶有兴趣地阅读了科尔德 - 瓦尔卡内等人的综述，该综述探讨了补充维生素D对人体胰岛素样生长因子 - 1（IGF - 1）水平的影响。我们认为这篇文章存在严重的方法学缺陷，因此其结论可能存在偏差。因此，作者应解决上述局限性并更新分析，以提供可靠且可信的估计。我们担心如果不进行修正，这些分析可能会导致错误的发现和结论。
