Classification of patients at different risk probability of suicide
The average threshold of the training (53.7%) and validation (24.6%) cohorts was regarded as the optimal cut-off value (40%). Based on the best cut-off value of the nomogram, patients in the high-risk group had a nearly 6-time larger likelihood of committing suicide by self-poisoning than patients in the low-risk group (88.68 vs. 15.38%, Patients stratified by risk group based on the optimal threshold of the nomogram.Indicates a comparison of actual probability between the low- and high-risk groups.
