Analysis of risk factors of suicidal ideation in adolescent patients with depression and construction of prediction model

Figure 4 The nomogram of suicidal ideation in internal validation. A: Receiver operating characteristic of the nomogram for predicting the probability of suicidal ideation (SI); B: Density curve analysis of the nomogram for predicting the probability of SI; C: Calibration curve of the nomogram for predicting the probability of SI. AUC: Area under the receiver operating characteristic curve; SF: Serum ferritin; hs-CRP: High-sensitivity C-reactive protein; HDL-C: High-density lipoprotein; DCA: Density curve analysis; SI: Suicidal ideation.
