Patients’ etiology of neuropathy, sensory profile, test areas of affected (neuropathic/painful) and non-affected (control) skin sites, and presence of lidocaine 5% patch analgesia defined as reduction of acute (spontaneous) pain at visit by NRS values exceeding 1. Note that 5 patients did not return the questionnaire and in 1 patient the sensory profile was not assessed (n/a).
