After adjusting confounding effects, only lymphocyte count (OR = 0.324, p = 0.034), SCr (OR = 1.052, p < 0.001), serum cystatin C (OR = 8.801, p = 0.017) and RBC transfusion (OR = 4.212, p = 0.005) were significantly associated with development of AKI during hospitalization. Here, CST3 is linked to acute kidney injury.
