Fig. 1From: Olipudase alfa enzyme replacement therapy for acid sphingomyelinase deficiency (ASMD): sustained improvements in clinical outcomes after 6.5 years of treatment in adults Assessment of Olipudase Alfa on Spleen Volumes A. Individual patient spleen volumes by years of olipudase alfa treatment. Spleen volumes were calculated by integrating cross-sectional magnetic resonance images and expressed as multiples of normal (MN) where normal spleen volume was assumed to be 0.2% of body weight [18]. Severe and moderate splenomegaly were defined as > 15 and > 5 to ≤ 15MN, respectively [18]. Cutoffs of MN for severity of splenomegaly are indicated by horizontal lines B. Least square (LS) mean percent changes ± SE of the mean in spleen volume from baseline over time. All p values are nominalBack to article page
