《生理学杂志》和《英国药理学杂志》于2011年联合发表了一系列社论，以提高统计报告和数据分析的标准。不知道是否根据编辑建议改变了报告做法。我们进行了一个横截面分析的报告实践中，在这些期刊发表的研究论文的随机样本之前（n = 202）和之后（n = 199）的编辑建议出版。提供了描述性数据。没有证据表明，在发表编辑意见后，报告做法有所改进。总体而言，76-84%的论文采用了平均值的标准误，90-96%的论文没有报告主要分析和事后检验的精确p值。76-84%的论文绘制了用于总结数据变异性的测量值，使用了平均值的标准误差，只有2-4%的论文绘制了用于计算变异性的原始数据。在报告p值在0.05和0.1之间的论文中，56-63%将其解释为趋势或统计学显著性。在发表编辑建议之前（n = 10）和之后（n = 9）的论文中偶然注意到隐含或严重旋转。总的来说，在编辑建议发表之前和之后，存在统计报告不佳、数据呈现不充分和旋转问题。虽然科学界继续实施改进报告做法的战略，但我们的结果表明，需要更强有力的激励或执行。
The Journal of Physiology and British Journal of Pharmacology jointly published an editorial series in 2011 to improve standards in statistical reporting and data analysis. It is not known whether reporting practices changed in response to the editorial advice. We conducted a cross-sectional analysis of reporting practices in a random sample of research papers published in these journals before (n = 202) and after (n = 199) publication of the editorial advice. Descriptive data are presented. There was no evidence that reporting practices improved following publication of the editorial advice. Overall, 76-84% of papers with written measures that summarized data variability used standard errors of the mean, and 90-96% of papers did not report exact p-values for primary analyses and post-hoc tests. 76-84% of papers that plotted measures to summarize data variability used standard errors of the mean, and only 2-4% of papers plotted raw data used to calculate variability. Of papers that reported p-values between 0.05 and 0.1, 56-63% interpreted these as trends or statistically significant. Implied or gross spin was noted incidentally in papers before (n = 10) and after (n = 9) the editorial advice was published. Overall, poor statistical reporting, inadequate data presentation and spin were present before and after the editorial advice was published. While the scientific community continues to implement strategies for improving reporting practices, our results indicate stronger incentives or enforcements are needed.
