ENO2 and perinatal asphyxia: This study aimed to determine whether neurological prognostic accuracy and sensitivity increased through replacing no-flow time information with data obtained from brain magnetic resonance imaging (MRI), computed tomography (CT), or biochemical indicators (neuron-specific enolase (NSE)), to more objective representing hypoxic ischemic encephalopathy occurring before TTM as a variable of the CA-specific risk score.
