GPT and intracranial hemorrhage: In the next step of univariate analysis (Table 2), younger age < 40 years old (odds ratio[OR] = 2.6, p = 0.001), DC due to intracranial hemorrhage (OR = 3.4, p = 0.004), GPT < 18 U/l at PT1 (OR = 2.4, p = 0.003), time between DC and cranioplasty > 95 days (OR = 1.83, p = 0.045), and serum creatinine < 0.851 mg/dl at PT2 (OR = 1.88, p = 0.032) were significant risk factors for ABFN.
