Table 2. Areas Under the Curve (95% CIs), Overall and Within Racial/Ethnic Subgroups, of Suicide Prediction Models^a.

Race/ethnicity	Logistic regression with LASSO	Random forest
Entire validation set	0.822 (0.811-0.832)	0.816 (0.806-0.825)
White	0.828 (0.815-0.840)	0.812 (0.800-0.826)
Hispanic	0.855 (0.822-0.885)	0.831 (0.799-0.859)
Black	0.775 (0.687-0.850)	0.786 (0.715-0.846)
Asian	0.834 (0.796-0.870)	0.882 (0.853-0.910)
American Indian/Alaskan Native	0.599 (0.513-0.686)	0.642 (0.579-0.710)
Not recorded	0.640 (0.598-0.681)	0.676 (0.638-0.714)

^aThe 95% CIs were obtained from 1000 visit–level bootstrap samples. Prediction model performance is not reported for visits made by patients who were Native Hawaiian/Pacific Islander, multiracial, or other race because there were fewer than 10 visits with a suicide death within 90 days in the validation data set (eTable 9 in the Supplement).
