Performance status assessment, Karnofsky performance status (KPS), and Eastern Cooperative Oncology Group (ECOG) scales were performed in 100 consecutive patients independently by two physicians and by the patients themselves to evaluate the scales' validity and reliability. Findings of Kendall's correlation were highly significant between physicians (0.76 for KPS, 0.75 for ECOG) and between physicians and patients (0.65 for KPS, 0.59 for ECOG). The authors point out that patients' self evaluation could provide a valuable and reliable assessment.
由两名医生和患者本人分别对100例连续患者进行了体能状态评估、卡诺夫斯基体能状态（KPS）评分及东部肿瘤协作组（ECOG）评分，以评估这些评分的有效性和可靠性。肯德尔相关性分析结果显示，医生之间（KPS为0.76，ECOG为0.75）以及医生与患者之间（KPS为0.65，ECOG为0.59）的相关性都非常显著。作者指出，患者的自我评估可以提供有价值且可靠的评估。
