Based on the Wald’s statistics, which assesses the relative contribution of each variable to the outcome in regression model, we hypothesized that the relative significance of miR-33a (Wald’s coefficient 4.3) in prediction of liver graft steatosis will be, at most, at par with clinical and laboratory parameters (waist circumference (Wald’s coefficient 13.6), glycaemia (Wald’s coefficient 4.5), ALT (Wald’s coefficient 4.93)) (Table 4). This evidence concerns the gene GPT and steatosis.
