Table 2. Sensitivity, specificity, and predictive values for the development of severe AKI using hematological cut-off values.

	Cut-off value	Sensitivity	Specificity	PPV	NPV
Admission platelet (×109/L)	17	0.39	0.96	0.93	0.52
	34	0.80	0.83	0.87	0.75
	62	0.98	0.41	0.71	0.95
Nadir platelet (×109/L)	17	0.59	0.96	0.95	0.62
	33	0.91	0.76	0.85	0.85
	49	0.98	0.39	0.70	0.95
Admission leukocyte (×109/L)	17.3	0.52	0.83	0.81	0.54
Peak leukocyte (×109/L)	18.7	0.64	0.74	0.78	0.59

PPV, positive predictive value; NPV, negative predictive value.
