Can diffusion tensor imaging predict cerebral palsy in term neonates with hypoxic ischemic encephalopathy?

Table 2 Agreement of the initial routine MRI with final outcome

		Outcome at 1 year		Sensitivity	Specificity	PPV	NPV	Accuracy	Agreement
		Normal	Abnormal^@	Sensitivity	Specificity	PPV	NPV	Accuracy	Agreement
Initial routine MRI	Normal	17	7	56.25	100	100	70.83	78.79	57% (kappa 0.57)
Initial routine MRI	Abnormal	0	9
χ² (p)		13.148^* (< 0.001^*)

Kappa coefficient was used for percentage of agreement
χ² (p) χ² and p values for chi square test for comparing between the two categories, NPV negative predictive value, PPV positive predictive value
*Statistically significant at p < 0.05
^@Abnormal outcome was assessed both clinically as cerebral palsy and by MRI as different patterns of brain injury
