value represents the value of comparisons between the low-ferritin group and the NRR group, while value represents the value of comparisons between the NRR group and the high-ferritin group. NRR: normal reference range; ICU: intensive care unit; LOS: length of stay; AKI: acute kidney injury; SOFA score: the sequential organ failure assessment.
