概括

许多神经成像研究引用了2009年的一份报告来证明未经纠正的统计值. 然而,大多数人并没有遵循其建议,这凸显了神经成像研究中引用和实践之间的差距.

科学领域:

神经成像是一种神经成像.
神经科学中的统计分析.
大脑成像方法的方法.

背景情况:

神经成像研究通常对多次比较进行正确,以控制错误阳性.
2009年利伯曼和坎宁汉的一份报告主张使用未经纠正的统计值来平衡I型和II型错误.

研究的目的:

为了审查最近的神经成像研究,引用了2009年的报告.
调查引用是否被用来证明未经纠正的门值.
评估报告中推的违约门的遵守情况.

主要方法:

搜索了2019-2022年间发表的文章,其中引用了利伯曼和坎宁汉的报告.
分析了引用文章中报道的统计值方法.

主要成果:

67.6%的引用论文使用该报告来证明其统计值.
这些论文中只有19.7%严格遵守推的未经校正的P < 0.005,k = 10或k = 20值.
超过一半使用了各种集群范围值 (例如,Punc < 0.001,k = 50) 没有明确的理由.

结论:

在引用和应用利伯曼和坎宁厄姆报告的建议之间存在显著的脱节.
未来的研究必须严格证明基于理论和参数的统计值.
通过共享神经成像数据和元数据,鼓励提高透明度.

Chi-square Analysis

Chi-square Analysis

The chi-square test is a statistical hypothesis test. It is used to check whether there is a significant difference between an expected value and an observed value. In the context of genetics, it enables us to either accept or reject a hypothesis, based on how much the observed values deviate from the expected values.
The chi-square test was developed by Pearson in 1990.
The first step of performing a Chi-square analysis is to establish a null hypothesis, which assumes that there is no real...

Magnetic Resonance Imaging

Magnetic Resonance Imaging

Magnetic resonance imaging (MRI) is a noninvasive medical imaging technique based on a phenomenon of nuclear physics discovered in the 1930s, in which matter exposed to magnetic fields and radio waves was found to emit radio signals. In 1970, a physician and researcher named Raymond Damadian noticed that malignant (cancerous) tissue gave off different signals than normal body tissue. He applied for a patent for the first MRI scanning device in clinical use by the early 1980s. The early MRI...
