Psychological and hematological factors associated with fatigue in patients with Crohn’s disease receiving pharmacological treatment

Figure 1 Receiver operating characteristic curve of the composite symptom score (0 to 4 - depression, anxiety, stress and insomnia and association with fatigue) in patients with Crohn disease treated at a referral center. Receiver operating characteristic curve analysis - symptomatic score, discriminative performance: Area under the curve: 0.775. Interpretation: (1) Between 0.7 and 0.8 to good discriminative capacity; (2) The model has a 77.5% chance of correctly classifying a random pair of individuals (one with fatigue and one without); and (3) This indicates that the score is useful for distinguishing individuals with and without fatigue with good accuracy. Previously determined at probability ≥ 0.827, which corresponds to approximately score ≥ 2. At this point, the performance was sensitivity: 54.6% and specificity: 91.3%. ROC: Receiver operating characteristic curve; AUC: Area under the curve.
