Figure 2:

Anterior Horn Width in relation to neurodevelopmental outcomes at 18–24 months in 39 preterm infants with PHVD. The maximal size of the AHW in the North American group of the study by Leijser et al, (yellow bar) and the corresponding neurodevelopmental impairments with performance at 60–70 points, contrasts with the results in the ELVIS study with early (red) and late (blue) demonstrating less significant differences in outcomes. It is noteworthy that timing of the “late” intervention arm in ELVIS is much earlier than in the North American sites.
