miR-15a-5p may be a biomarker for acute kidney injury (AKI) in patients with sepsis treated by gentamicin. Data are presented as log 2–transformed label-free quantification of miRNA serum concentrations and expression. a Serum concentrations of miR-15a-5p in patients with AKI versus non-AKI in the gentamicin group; p values are from the Mann–Whitney U test. b Relative receiver operating characteristic (ROC) curve with the area under the curve obtained from by simple logistic regression; ** log-likelihood ratio test, p = 0.008
