Figure 6:

Quantitative sensory testing data, divided by non-responders versus responders (>50% pain reduction at 60-120 minutes with lidocaine but not placebo.) Non-responders denoted with blue, responders denoted with red. * indicates P value < .05. CDT = Cold Detection Threshold (−1.6 [−2.7 to −0.8] versus −0.8 [−0.9 to −0.5]). WDT = Warm Detection Threshold (−1.6 [−2.2 to −1.3] versus −1.3 [−1.4 to −1.0]). CPT = Cold Pain Threshold (−0.6 [−0.9 to 0.5] versus 0.3 [−0.5 to 0.7]). HPT = Heat Pain Threshold (−1.4 [−1.8 to −0.8] versus −0.6 [−1.2 to 0.7]). MDT = Mechanical Detection Threshold (−1.7 [−3.7 to −1.1] versus −2.0 [−2.6 to −1.3]). MPT = Mechanical Pain Threshold (−1.9 [−2.7 to −0.3] versus −1.3 [−2.4 to −0.8]). WUR = Wind Up Ratio (−0.4 [−0.8 to 0.3] versus 0.3 [−1.0 to 1.1]). VDT = Vibration Detection Threshold (−2.3 [−4.5 to −1.50] versus −2.5 [−3.7 to −2.1]).
