• Maximum KIM-1 levels did not differ between those with and without AKI • Compared to survivors, non-survivors had higher KIM-1     ° Non-survivors: 385 pg/mL (95% CI 231, 1,028)     ° Survivors: 264 (95% CI 147, 549)     ° For every 100 pg/mL rise in KIM-1, there was a 10% higher odds of death (OR 1.1 (1.0–1.2), p < 0.02; AUC 0.64). This evidence concerns the gene HAVCR1 and acute kidney injury.
