There was a significant relationship between urinary KIM-1 levels of 1.666 ng/ml and the occurrence of AKI in septic patients with p-value = 0.000 and RR of 6.866 (95$ CI, 3.329–14.165), which means that septic patients with urinary KIM-1 levels ≥1.666 ng/ml have a higher risk of AKI than those with urine KIM-1 <1.666 ng/ml. Here, HAVCR1 is linked to acute kidney injury.
