In their correspondence, Hays et al. raise two main critiques of our recently published article entitled "Use of the KDQOL-36™ for assessment of health-related quality of life among dialysis patients in the United States." First, Hays et al. expressed concerns regarding the comparison of mean scores on five Kidney Disease Quality of Life (KDQOL) subscales, given that the Physical Component Summary (PCS) and Mental Component Summary (MCS) are scored on a different numeric scale compared to the other three subscales. Second, Hays et al. note that the correlations reported in our manuscript between the general health perceptions item ("In general, would you say your health is excellent, very good, good, fair, or poor") and the 5 KDQOL subscales were inconsistent with findings derived from other KDQOL datasets. Here, we respond to these two critiques.

回应Hays及其同事关于我们的论文的信，该论文题为“使用KDQOL-36™评估美国透析患者健康相关的生活质量”。

在他们的通信中，海斯等。对我们最近发表的文章“在美国透析患者中​​使用KDQOL-36™评估健康相关生活质量的使用”提出了两个主要批评。首先，海斯等。表示关注比较五个肾脏疾病生活质量（KDQOL）子量表的平均评分，因为与其他三个子量表相比，身体成分摘要（PCS）和心理成分摘要（MCS）的评分数字不同。第二，海斯等。请注意，我们手稿中报告的一般健康感知项目（“通常，您会说您的健康状况非常好，非常好，好，一般或差”）与5个KDQOL分量表之间的相关性与其他KDQOL数据集。这里，
