Fig. 5. Comparison of pain profiles among patients with different CDT and QSART results. The group with only abnormal CDT findings had more-severe stabbing pain compared to the group with both abnormal CDT and abnormal QSART findings in multiple logistic regression analysis after controlling for age, sex, and disease duration. A: burning pain, B: squeezing pain, C: pressure pain, CDT: cold detection threshold, D: stabbing pain (^*), E: electric-shock-like pain, F: brush-evoked pain, G: pressure-evoked pain, H: cold-evoked pain, I: pins-and-needles sensation, J: tingling sensation, K: ‘Sirim’ pain, NRS: numerical rating scale, QSART: quantitative sudomotor axon reflex test.
