Comparison of composite scores for motor maturity and body weight between Krabbe-affected and normal infants. A: Infants identified as affected in the first month after birth received the Infant Neurobehavioral Assessment. Thereafter they were assessed using the Modified Bayley Scales of Infant Development. Motor maturity for each Krabbe-affected subject was plotted (colored bars), and the mean and SD for normal, unaffected infant rhesus macaques (n = 24) from the TNPRC are presented as a line graph with error bars. B: Comparison of the Krabbe-affected subjects’ weights. Weight of Krabbe-affected animals was monitored monthly throughout their lives and compared with that of the mean and SD of normal, unaffected rhesus macaques (n = 24) from the TNPRC.
