Fig. 2From: Is there an added value of faecal calprotectin and haemoglobin in the diagnostic work-up for primary care patients suspected of significant colorectal disease? A cross-sectional diagnostic studyReceiver operating characteristic curves for diagnosing SCD for the basic diagnostic model, and the POC FIT and the calprotectin POC test extended models. FIT faecal immunochemical test for haemoglobin; POC point-of-care; SCD significant colorectal disease. Areas under the curve (before optimism-correction): basic model 0.741 (95Ā % CI, 0.694ā0.789); calprotectin POC test extended 0.763 (95Ā % CI, 0.718ā0.809); POC FIT extended 0.831 (95Ā % CI, 0.791ā0.872); Both faecal POC tests extended 0.837 (95Ā % CI, 0.798ā0.876).
