The strength of research conclusions must follow from the strength of evidence. In this commentary I raise several issues with a recent paper "Brain structure changes induced by attention bias modification training" (Abend et al., 2019). I follow the paper's five highlights to discuss; the absence of discussion of negative ABM results, the low power of the study itself. Centrally, I raise the concern that the conclusions rest all their weight on a single statistically significant group x time interaction form brain-wide analysis. Most importantly, this test is not internally consistent following statcheck. The reported result requires checking, and potentially a correction that would shift the results entirely.

注意偏差修正会导致大脑结构变化吗？对 Abend 等人的评论。(2019)

研究结论的强度必须来自证据的强度。在这篇评论中，我在最近的一篇论文“注意力偏差修正训练引起的大脑结构变化”（Abend 等人，2019 年）中提出了几个问题。我按照论文的五个亮点来讨论；没有讨论负 ABM 结果，研究本身的低功率。集中地，我提出了一个担忧，即结论的全部权重都依赖于单个具有统计意义的组 x 时间交互形式的全脑分析。最重要的是，此测试在 statcheck 后内部不一致。报告的结果需要检查，并且可能需要进行可能完全改变结果的更正。
