Validity of diagnostic criteria for chronic inflammatory demyelinating polyneuropathy: a multicentre European study

Abstract

In our patient populations, the EFNS/PNS criteria were the most sensitive and allowed identification of a highly significantly greater number of patients than Koski et al's criteria. The latter were comparable in specificity with the "definite/probable" EFNS/PNS electrodiagnostic subcategories. More extensive nerve-conduction studies improved diagnostic yield but resulted in loss of specificity.
