Answer

The wide variability in symmetric diabetic polyneuropathy prevalence data is due to lack of consistent criteria for diagnosis, variable methods of selecting patients for study, and differing assessment techniques. In addition, because many patients with diabetic polyneuropathy are initially asymptomatic, detection is extremely dependent on careful neurologic examination by the primary care clinician. The use of additional diagnostic techniques, such as autonomic or quantitative sensory testing, might result in a higher recorded prevalence. [37, 38]
