Fig. 4From: Diagnosis of inflammatory peri-implant diseases using an immunochromatographic assay for calprotectin in peri-implant crevicular fluidROS analysis of PICF calprotectin amount determined using an IC reader to predict peri-implant diseases. a The IC reader value of calprotectin in PICF samples from the inflammatory diseased sites (n = 57) and healthy sites (n = 42) was compared. Horizontal bars show the mean values of the inflammatory and healthy groups. **P < 0.01. b The IC reader value of PICF calprotectin amount was subjected to ROC curve analysis. AUC value for the IC reader value of calprotectin amount was 0.908 (95% CI 0.847–0.969, P < 0.001). When the cutoff value was 5.0, the sensitivity and specificity were 84.2% and 85.7%, respectivelyBack to article page
