Predictors of Good Long-Term Renal Outcomes in Lupus Nephritis: Results from a Single Lupus Cohort

Table 4

Performance of proteinuria cut-offs at 1 year to predict good long-term renal outcomes in subgroup of patients with baseline proteinuria ≥ 1 g/d.

24H-P at 1 year	Sensitivity	Specificity	PPV	NPV
0.61	0.51	0.77	0.90	0.29
0.66	0.52	0.70	0.87	0.26
0.82	0.56	0.69	0.88	0.28
0.90	0.60	0.69	0.89	0.30
0.94	0.62	0.69	0.89	0.31
0.95	0.63	0.69	0.89	0.32
1.01	0.63	0.62	0.86	0.30

PPV = positive predictive value; NPV = negative predictive value. Best cut-off by Youden index.
