However, multivariate analyses of all 57 neonates revealed that biochemical markers of hypoxia such as lactate (p = 0.100826), TnT (p = 0.218603), AST (p = 0.957588), ALT (p = 0.285924), creatinine (p = 0.794386), or urea (p = 0.306928) had no effect on the probability of survival of patients with HIE (Table 3). This evidence concerns the gene GPT and perinatal asphyxia.
