Different superscripts indicate a significant difference in post-hoc test (Dunn-Bonferroni-Test)

HADS, Hospital Anxiety and Depression Scale; IQR, interquartile range; SD, standard deviation; NODAT, new-onset diabetes after transplantation; eGFR, estimated glomerular filtration rate. Statistically significant results (p < .05, p < .01 and p < .001) are shown in boldface.
