BACKGROUND
Statistical error rates in the medical literature are generally high.
METHOD
All papers published in the British Journal of Psychiatry in 1993 which presented numerical results were reviewed by the author for statistical errors.
RESULTS
A total of 248 papers were published, of which 164 (66%) presented numerical results. Sixty-five (40% of 164) papers contained statistical errors. Many errors were not serious in nature, but some were serious enough to cast doubt on conclusions. The error rates are similar to those found in an earlier study.
CONCLUSIONS
The statistical error rate is unacceptably high. There is no evidence of a change in the statistical error rate over time.
背景
医学文献中的统计错误率普遍较高。
方法
作者对1993年发表在《英国精神病学杂志》上所有呈现数值结果的论文进行了统计错误审查。
结果
共发表了248篇论文，其中164篇（66%）呈现了数值结果。65篇论文（占164篇的40%）存在统计错误。许多错误性质并不严重，但有些错误严重到足以让人对结论产生怀疑。这些错误率与早期一项研究中的发现相似。
结论
统计错误率高得令人无法接受。没有证据表明统计错误率随时间有所变化。
