(a) Partial regression plot showing the relationship between FA values and number of days requiring mechanical ventilation in data extracted from the most significant voxel (r = 0.398) highlighted in the crosshairs in the axial (b) and coronal (c) plane. GA at birth, PMA at scan and gender were included as covariates in the model. Key: FA | X = residuals of FA given the model; Number of days on mechanical ventilation | X = residuals of number of days on mechanical ventilation given the model.
