Evaluating the clinical utility of an easily applicable prediction model of suicide attempts, newly developed and validated with a general community sample of adults

Table 4 Logistic regression prediction performance results across 100 cross-validations

Predictor	Min	1st Qu.	Mean	Median	3rd Qu.	Max
PR AUC	0.028	0.074	0.132	0.106	0.163	0.436
ROC AUC	0.644	0.771	0.805	0.800	0.846	0.916
ICI	0.003	0.006	0.008	0.008	0.010	0.018

Note. Min = minimum; 1st Qu. = 25% quantile; 3rd Qu. = 75% quantile; Max = maximum; PR AUC = area under the precision-recall curve; ROC AUC = area under the receiver operating characteristic curve; for both, a value of 1 represents perfect discrimination; ICI = Integrated Calibration Index; a value of 0 for the ICI represents perfect calibration
