  1. Univariate logistic mixed model analyses toward diagnostic EVDI status change. No variable can be seen to predict change of status. The variable repositioning could, however, not be included in this analysis computationally due to zero events in the C-samples, thus noted not applicable (NA), but was seen statistically significant (\(p=.042\)) with a Chi-Squared test. IVH volume, sediment depth, catheter distance, and IVHS are defined in the methods section. IVHS: Intraventricular Hemorrhage Score, see methods section. EVDI: External Ventricular Drain Infection. GCS: Glascow Coma Scale. GCS motor: Glascow Coma Scale motor response
