Consistent with prior studies, the findings indicated that adequate ferritin levels (100–700 ng/ml) were associated with a higher incidence of AKI, while low ferritin levels (<100 ng/ml) were associated witha reduced risk of AKI—particularly among postmenopausal women, individuals aged 18–64, and those with CRP > 10 mg/L—supporting the role of inflammation in increasing AKI risk. Here, CRP is linked to acute kidney injury.
