Trial Outcomes & Findings for A Multi-Center Study to Assess the Performance of Saturation Patterns. (NCT NCT00775346)
NCT ID: NCT00775346
Last Updated: 2014-08-07
Results Overview
Sensitivity and specificity were computed from the count of instances in which the Saturation Pattern Detection (SPD) index value (vs. Polysomnography) within a discrete ten minute interval correctly identified a Repetitive Reduction in Airflow (RRiA) as being present within that interval (True Positive), absent (True Negative), or incorrectly identified presence or absence (False Positive and False Negative, respectively). Sensitivity is True Positive divided by True Positive plus False Negative TP/(TP+FN). Specificity is True Positive divided by True Negative plus False Positive TP/(TN+FP).
