  • a We set sensitivity at 0.60, 0.70, and 0.80 for each model and show the corresponding specificity, cutoff score (rounded to the nearest whole number), and estimated proportion of the population screening positive, at or above each cutoff score, weighted to reflect ECLS-B sampling design. The corresponding sensitivities and specificities of the BSF-R mental scale are also shown, for comparison.
