概括
当将严重正常和轻微异常类别结合成亚临床分类时,平滑追踪 (SP) 眼动评估的临床协议得到了改进. 计算机化指标也显示了对分类SP的良好的敏感性和特异性.
科学领域:
- 眼科医生 眼科 眼科
- 神经科学是一个神经科学.
- 生物医学工程 生物医学工程
背景情况:
- 顺追踪 (SP) 眼动评估从定性和定量数据中受益.
- 目前眼睛追踪技术的进步需要探索SP的最佳分类方法.
- 这项研究解决了在临床SP评估中提高一致性的需求.
研究的目的:
- 评估使用标准类别评估SP的临床医生之间的评价者之间的可靠性.
- 确定将"粗略正常" (GN) 和"轻微异常" (MA) 结合成"亚临床" (SUBC) 类别是否会改善共识.
- 为了评估SP分类的计算机化百分比萨卡德 (PS) 度量的灵敏度和特异性.
主要方法:
- 70名参与者的横向和垂直SP眼睛跟踪视频和数据的回顾性分析.
- 三位临床医生使用4个类别 (正常,GN,MA,AB) 然后3个类别 (正常,SUBC,AB) 评价SP表现.
- 计算机化百分之三度 (PS) 度的灵敏度和特异性是使用生成的截止值来计算的.
主要成果:
- 在使用4个SP类别的临床医生中观察到公平的总体协议.
- 将GN和MA结合到一个SUBC类别中,导致横向SP (HSP) 和垂直SP (VSP) 之间的分级协议略有改善.
- 当两个或更多频率的值被超过时,PS指标表现出良好的灵敏度和特异性.
结论:
- 将"严重正常"和"轻微异常"类别结合为"亚临床"分类,提高了临床医生对SP评估的共识.
- 计算机化的百分比萨卡德度量是客观SP分类的宝贵工具.
- 整合定性和定量数据可以改善对平滑追踪眼动的全面评估.

Multiple Comparison Tests
Multiple comparison test, abbreviated as MCT, is a post hoc analysis generally performed after comparing multiple samples with one or more tests. An MCT will help identify a significantly different sample among multiple samples or a factor among multiple factors.
It would be easy to compare two samples using a significance alpha level of 0.05. In other words, there is only one sample pair to be compared. However, it would be difficult to identify a significantly different sample if the number...

Wald-Wolfowitz Runs Test II
The Wald-Wolfowitz runs test, commonly referred to as the runs test, is a nonparametric test used to assess the randomness of ordered data. The test evaluates the number of runs, which are consecutive sequences of similar elements within the data. If the number of runs is significantly higher or lower than expected, the data is considered non-random, indicating a detectable pattern or structure.
For binary data, runs are identified using symbols such as + and −, or equivalently, 1s and 0s. In...
