KDIGO criteria for AKI Stage 2: which description defines it?

KDIGO AKI stages are defined by how much creatinine rises from baseline and by how much urine is produced. Stage 2 is a moderate loss of function: creatinine is 2.0–2.9 times the patient’s baseline, or urine output falls below 0.5 mL/kg per hour for 12 hours. This places it above stage 1 (1.5–1.9 times baseline or urine output 0.5 mL/kg/h for 6–12 h) but below stage 3 (creatinine ≥3 times baseline or urine output <0.3 mL/kg/h for ≥24 hours, or anuria for ≥12 hours, or need for renal replacement therapy). The description mentioning urine output greater than 1.0 mL/kg/h does not reflect AKI.
