Variation between neonatal intensive care units (NICUs) A–F in the reported quality and completeness of scans
| A | B | C | D | E | F | Total | |
|---|---|---|---|---|---|---|---|
| The proportion of scans that were incomplete or of poor quality varied between NICUs, p<0.001. The values are number (%) of reports for each NICU. Scans may be included in more than one category—for example, because the reviewer was able to report on the appearance of the ventricles but not the parenchyma. | |||||||
