Fig. 2

Biplot of objective neurosensory measurements. An acute angle indicates a positive correlation. A 90-degree angle indicates no correlation between the two variables, and an obtuse angle indicates a negative correlation. The more similar the direction of two vectors, the stronger the correlation between these variables. This biplot shows a strong correlation between two-point discrimination, Sunderland score, loss-of-function sensory code and percentage of affected dermatome. Also, directional discrimination, stimulus localization, and MRCS score show a strong correlation. Gain-of-function sensory code and brush stroke allodynia show a strong correlation with each other but are far less correlated with the other variables
