Lower OHI final values were significantly correlated with post-operative sepsis (0.641 vs. 0.705, p = 0.045), while ΔOHI was correlated with pre-operative hypertension (−0.125 vs. −0.019, p = 0.013) and PHLF (−0.075 vs 0.023, p = 0.010), as well as a negative correlation with ALT values on POD 5 (r = −0.813, p = 0.001). This evidence concerns the gene GPT and hypertensive disorder.
