Failure to Identify the Left Arcuate Fasciculus at Diffusion Tractography Is a Specific Marker of Language Dysfunction in Pediatric Patients with Polymicrogyria

Table 1

Diagnostic performance of absence of the left arcuate fasciculus for prediction of language impairment.

	Diagnostic performance	95% LCI	95% UCI
Sensitivity (%)	78	40.1	96.1
Specificity (%)	100	56.1	100
PPV (%)	100	56.1	100
NPV (%)	78	40.1	96.1

LCI: lower limit of the 95 percent confidence interval; UCI: upper limit of the 95 percent confidence interval; PPV: positive predictive value; NPV: negative predictive value.
