GPT and vitamin D deficiency: Furthermore, in model 2, after adjusting for further confounders (waiting time for transplantation, medical condition at the time of LT, causes of cirrhosis, smoke, alcohol, hypertension, diabetes mellitus, and infection of CMV) and final model (further adjustment for MELD-Na, AST, ALT, PMN, WBC, and lymphocytes), vitamin D deficiency was associated with 2.68- (OR: 2.68; 95% CI 1.59–4.71, P for trend = 0.001) and 2.69-fold (OR: 2.69; 95% CI 1.50–4.68, P for trend = 0.001) increase in the odds of ACR, respectively.
