After adjustment for confounding factors, maternal serum TBA and ALT were the independent risk factor for neonatal ORN metabolic disorders [(adjusted odds ratio (AOR) = 0.379, 95%CI = 0.188–0.762, p = 0.006), (AOR = 0.441, 95%CI = 0.211–0.922, p = 0.030)]. Here, GPT is linked to Other metabolic disease.
