A recent article in the journal reported analyses of KDQOL-36™ survey data collected from 240,343 adults (330,412 surveys) dialyzed at a large dialysis organization in the United States during 2014-2016. The authors concluded that the KDQOL-36™ Symptoms and Problems of Kidney Disease scale had the highest mean score of the KDQOL-36™ scales. We note that this inference was erroneous because the scales are not scored on the same numeric scale. In addition, the authors found that responses to a general health perceptions item ("In general, would you say your health is excellent, very good, good, fair, or poor") was not significantly associated with any of the 5 KDQOL-36 scale scores. In contrast, we find significant and noteworthy correlations in two other datasets. These analytic issues call into question the accuracy and validity of the conclusions of this paper.

“使用 KDQOL-36™ 评估美国透析患者健康相关生活质量”中的数据分析和解释问题。


该杂志最近的一篇文章报告了对 2014-2016 年在美国一家大型透析机构接受透析的 240,343 名成年人（330,412 项调查）收集的 KDQOL-36™ 调查数据的分析。作者得出的结论是，KDQOL-36™ 肾脏疾病症状和问题量表的平均得分最高。我们注意到这个推论是错误的，因为这些量表不是在相同的数字量表上评分的。此外，作者发现，对一般健康认知项目（“一般来说，您会说您的健康状况非常好、非常好、好、一般还是差”）的反应与 5 个 KDQOL-36 中的任何一个都没有显着相关量表分数。相比之下，我们在其他两个数据集中发现了显着且值得注意的相关性。这些分析问题使人们对本文结论的准确性和有效性提出质疑。
