- The presented measures pertain to the performance of the Y-ACNAT-NO in the validation sample.
- aIf a test score on the Y-ACNAT-NO (i.e., the probability of future care needs) is greater than the cutoff score, the test result is considered positive; otherwise, it is considered negative. The cutoff score with the highest Youden index [J] is indicated in bold.
- CI = Confidence interval; NND = Number needed to detain; NSD = Number safely discharged.
