From: Correlation between the accumulation of skin glycosylation end products and the development of type 2 diabetic peripheral neuropathy

Test variable Positive if greater than or equal to a Sensitivity 1-Specificity Specificity Youden index
AGEs cumulants 77.65 .731 .291 0.709 0.440
Neuropathy risk score 66.2500 .676 .291 0.709 0.385
  1. Test variable: AGE, neuropathy scores had at least one knot between positive and negative actual status groups. aThe minimum boundary value is the minimum observation and test value minus 1, and the maximum boundary value is the maximum observation and test value plus 1. All other boundary values are the average of two adjacent observational test values
