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

Table 3

Performance of proteinuria and serum Cr cut-offs at year 1 to predict good long-term renal outcomes at 7 years.

Measures	Sensitivity; (95% CI)	Specificity; (95% CI)	PPV; (95% CI)	NPV; (95% CI)
24H-P < 0.57 g/d	0.58 (0.47–0.69)	0.83 (0.67–0.98)	0.92 (0.84–0.99)	0.36 (0.23–0.50)
Cr < 83 mmol/L	0.82 (0.73–0.91)	0.78 (0.61–0.95)	0.93 (0.87–0.99)	0.56 (0.39–0.73)
24H-P < 0.57 g/d and Cr < 83 mmol/L	0.51 (0.40–0.62)	0.96 (0.87–1.00)	0.98 (0.93–1.00)	0.37 (0.24–0.49)

Note. PPV: positive predictive value; NPV: negative predictive value; CI: confidence intervals.
