Fig. 4From: Early progression of Krabbe disease in patients with symptom onset between 0 and 5 monthsCSF protein levels. CSF protein levels were plotted against patient age. The red diamonds represent the CSF protein level at a single point in time. Levels from the same individual, but at different points in time, are connected by red lines. The blue shaded area represents 95% variability of CSF protein level of the normal population by ageBack to article page
