Literature classification criteria.

Prospective study. Diagnosis of disease in the patient population based on clinical criteria independent of the electrodiagnostic procedure under evaluation. Electrodiagnostic procedure described in sufficient detail, or reference provided to a published technique, to permit duplication of the procedure. Body temperature monitored and reported. Reference values for the electrodiagnostic procedure obtained with either (a) concomitant studies of a reference population or (b) previous studies of a reference population in the same laboratory. Criteria for abnormal findings clearly stated, and defined in statistical terms, e.g., range, mean + 2 standard deviations (SD), from data derived from the reference population.
