在撰写稿件时，我们经常使用完美、强、好或弱等词语来命名变量之间关系的强度。然而，目前还不清楚良好的关系在哪里会变成牢固的关系。同样强度的r被不同的研究者命名。因此，在稿件中报告相关系数的同时，明确报告r的强度和方向是绝对必要的。本文旨在使医学读者熟悉医学论文中报道的几种不同的相关系数，澄清混淆方面，并总结相关系数强度的命名实践。
When writing a manuscript, we often use words such as perfect, strong, good or weak to name the strength of the relationship between variables. However, it is unclear where a good relationship turns into a strong one. The same strength of r is named differently by several researchers. Therefore, there is an absolute necessity to explicitly report the strength and direction of r while reporting correlation coefficients in manuscripts. This article aims to familiarize medical readers with several different correlation coefficients reported in medical manuscripts, clarify confounding aspects and summarize the naming practices for the strength of correlation coefficients.
