Intra- and Inter-Operator Percent Match in Shape Classification by Morphologic Type.

Comparison of intra-operator (C1�CC2) and inter-operator variability between human operators (A�CB; C1-A; C1-B) and between the automated (NeuronStudio) spine classification and the human consensus (NS-HC). Variability is measured by pairwise percent match: higher percent match indicates lower variability between operators. Overall, NeuronStudio's classification matched the HC standard equally, or better than, the best human inter-operator match.

本研究对比了两种变异性：其一为人类操作者的操作者内部变异性（C1–C2）与操作者间变异性（涉及操作者对A–B、C1–A、C1–B）；其二为自动化树突棘分类工具（NeuronStudio）的分类结果与人类共识标注（NS-HC）之间的变异性。变异性通过两两匹配百分比进行量化：匹配百分比越高，代表比对双方的变异性越低。总体而言，NeuronStudio的分类结果与人类共识标准的匹配程度，至少与最佳的人类操作者间匹配结果持平，甚至更优。
