Percentages of patients with intracranial hypertension (IH) and negative (NPV) and positive (PPV) predictive values at the three intracranial pressure (ICP) thresholds. a Percentage of patients with ICP above (red silhouette indicating IH) and below (green silhouette indicating normal ICP) the given ICP thresholds of 20, 22 and 25 mmHg. b NPV and PPV (%) of the averaged time frames (T1,2,3) at the three ICP thresholds (20, 22 and 25 mmHg). NPV = green silhouette indicating true negatives and grey silhouette indicating false negatives. PPV = red silhouette indicating true positives and grey silhouette indicating false positives
