概括
在中风护理中,护理过程时间的测量通常是歪曲的. 在超急性中风试验和系统性审查中,建议使用基于中位数的统计数据,而不是基于平均值的统计数据.
科学领域:
- 医疗干预 医疗干预
- 临床试验分析
- 系统审查是系统的审查.
背景情况:
- 在评估超急性中风干预和护理系统方面,护理过程时间的测量是至关重要的.
- 基于平均值的统计数据可能会误导歪曲的时间数据.
- 基于百分比的统计数据,就像中位数一样,提供了对治疗时间的公正总结.
研究的目的:
- 调查超急性中风试验中的护理过程时间测量的报告和统计比较.
- 为未来涉及这些时间尺度的元分析提供方法论基础.
主要方法:
- 一项对146项报告高急性中风治疗时间指标的研究的系统范围审查.
- 分析基于转换的方法与实际的护理过程时间数据之间的统计一致性.
- 基于平均值和百分位数的元分析技术的图形和统计比较.
主要成果:
- 34%的研究报告仅使用平均值/SD进行时间测量,可能产生不可能的负值.
- 基于转换的归算方法与真标准偏差 (CCC=0.88) 有中等一致性.
- 基于平均值和中位数的元分析在跨臂效应方面产生了可比的结果,但在单独的手臂措施方面有所不同.
结论:
- 脑卒中研究人员应使用中位数/四分位数范围来总结时间指标,并采用基于等级的分析.
- 在使用基于转换的方法来赋值时间尺度的平均值/SD时,建议谨慎使用.
