Correlation coefficient, bias and limits of agreement between MLS measurement with sonography versus CT (method 2) in subgroups of patients where the pathology could adversely affect the sonographic measurement
| Patient characteristics | Number | r 2 | Bias (cm) | Limits of agreement (cm) |
|---|---|---|---|---|
| Decompressive craniectomy | 12 | 0.85 | 0.09 | -0.66 – 0.48 |
| Intracranial hematoma (SDH, EDH, IPH) | 28 | 0.64 | 0.09 | -1.29 – 1.11 |
| Subcutaneous temporal hematoma | 13 | 0.83 | 0.14 | -1.14 – 0.87 |
| MLS >0.5 cm | 19 | 0.69 | 0.22 | -1.84 – 1.39 |
| Invasive ICP >20 mmHg | 9 | 0.70 | 0.00 | -0.96 – 0.96 |
CT, computed tomography; EDH, extradural hematoma; ICP, intracranial pressure; IPH, intraparenchymal hematoma; MLS, midline shift; SDH, subdural hematoma.
