Table 3

Clinical performance characteristics of two consecutive fecal-calprotectin < 250 μg/g as a surrogate marker of mucosal healing after treatment for active ulcerative colitis.

Sensitivity (95% CI) (%)84.2 (60.4–96.6)
Specificity (95% CI) (%)100 (2.5–100)
PPV (95% CI) (%)100 (79.4–100)
NPV (95% CI) (%)25.0 (0.6–80.6)

CI: confidence interval; PPV: positive predictive value; NPV: negative predictive value.
