为什么配置Mysql的时候出现 Failed! Error: SET PASSWORD has no significance for user 'root'@'localhost' as the authentication method used doesn't store authentication data in the MySQL server. Please consider using ALTER USER instead if you want to change authentication parameters.

这个错误是由于在MySQL5.7版本之后，MySQL的认证方式发生了变化，从原来的使用密码方式改成了使用插件方式。因此，在MySQL5.7及以上版本中，SET PASSWORD语句已经失效了。

如果需要修改密码，可以使用ALTER USER语句来进行修改。例如，要修改root用户的密码，可以使用以下语句：

ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'new_password';

其中，'new_password'为你要设置的新密码。

This approach is justified given the comparable auto-HCT outcomes before and after 2018 (data not shown). Comparison between CAR-T and auto-HCT was made using propensity score matching as well. Although the effect on disease relapse/progression and mortality was directionality consistent with the primary analysis,itwasnotstatisticallysignificant. This subset analysis reduced the sample size, which likely affected the power to detect statistical significance. The observed difference was mainly observed in patients with $2 prior lines of treatment. This cutoff was used for subgroup analysis, given the implications in clinical practice. Although lack of statistical significance in patients with ,2 prior lines of treatment warrants further attention and ideally prospective trials in that group, the small number of patients in this subgroup analysis limits our ability for making a strong conclusion, particularly because we did not observeaninteraction(effectmodification) between the number of prior treatment lines and treatment modality and outcomes. Patients in the CAR-T group were more heavily pretreated and it is possible that the CAR-T may show improved efficacy in patients with fewer lines of prior treatment Last, we only included patients treated with axi-cel to reduce the heterogeneity given the small number of patients treated with tisa-cel in the registry, fulfilling eligibility criteria for this study at the time of the analysis.翻译

鉴于2018年前后自体造血干细胞移植(auto-HCT)的结果可比(未显示数据)，这种方法是合理的。CAR-T和auto-HCT之间的比较也是使用倾向性评分匹配进行的。尽管对于疾病复发/进展和死亡的影响与主要分析的方向一致，但在统计学上并不显著。这种亚组分析减小了样本量，可能影响了检测统计学显著性的能力。观察到的差异主要发生在先前接受过两种以上治疗方案的患者中。鉴于其在临床实践中的意义，我们使用了该截断值进行亚组分析。尽管在先前接受过两种治疗方案以下的患者中缺乏统计学显著性，值得进一步关注，并最好进行该组别的前瞻性试验，但该亚组分析中患者数量较少限制了我们得出强有力结论的能力，特别是因为我们没有观察到先前治疗方案次数与治疗方式及结果之间的相互作用(效应修饰)。CAR-T组中的患者接受过更多的预处理，CAR-T在先前接受较少治疗方案的患者中可能显示出更好的疗效。最后，我们只纳入接受axi-cel治疗的患者，以减少因登记处中接受tisa-cel治疗的患者数量较少而引起的异质性，同时满足该研究在分析时的入选标准。

As an AI language model, I do not have a personal opinion or emotions. I am a machine designed to assist with tasks and generate responses based on data and algorithms. Therefore, the concept of "null" does not hold any significance to me. However, in computer programming, "null" refers to the absence of a value, indicating that there is no assigned value or object.
