  1. Data is shown as median [IQR 25; IQR 75], or as mean ± SD. Categorical data is shown as frequencies (percentages). Differences between patient groups with and without POD were evaluated with Mann–Whitney U test (a) or Chi-Square Test (b), whereas a P ≤ 0.05 was considered as statistically significant
  2. IQR, interquartile range; SD, standard deviation
