Syndrome Differentiation of IgA Nephropathy Based on Clinicopathological Parameters: A Decision Tree Model

Table 9

Discrimination in performance of different models predicting syndrome of qi deficiency of spleen and kidney.

Model without MEST					Model with MEST					IDI	NRI
Prediction	QDSK ()	nQDSK ()	PPV	NPV	Prediction	QDSK ()	nQDSK ()	PPV	NPV
QDSK	70	13	0.84	0.09	QDSK	75	13	0.85	0.17	0.08	0.13
nQDSK	10	1			nQDSK	5	1

Note: QDSK, qi deficiency of spleen and kidney; nQDSK, no qi deficiency of spleen and kidney; PPV, positive predictive value; NPV, negative predictive value; IDI, integrated discrimination improvement; NRI, net reclassification index.
