Fig. 3From: A novel nomogram to stratify quality of life among advanced cancer patients with spinal metastatic disease after examining demographics, dietary habits, therapeutic interventions, and mental health statusProbability density curve between patients without (negative, green) and with (positive, red) poor quality of life. A The training set; B The validation set. Probability density curves were plotted against predicted probability. Among the patients with poor quality of life (green), the peak of its curve was located at a high level of predicted probability, while the peak of its curve was located at a low level of predicted probability among the patients without poor quality of life (red), suggesting that the nomogram had favorable discriminative abilityBack to article page
