CI: confidence interval; DC: derivation cohort; VC: validation cohort; DVT: deep vein thrombosis; TP: true positive; FP: false positive; TN: true negative; FN: false negative. Because we could never achieve high specificity with the head of bed elevation in the derivation cohort, we did not attempt validation. Only patients on sedation at any point during the test day were assessed for “sedation break.” |
