Figure 4. Initial symptoms in later onset MSA patients and usual onset MSA patients in each cohort.
(A) In the clinical cohort, the fraction of patients who presented with autonomic dysfunction as initial symptoms were 14% in LO-MSA (1/7) and 13% in UO-MSA (10/76).
(B) In the autopsy cohort, none of the LO-MSA patients had autonomic dysfunction as their initial symptom. In UO-MSA, the fractions of patients whose initial symptoms were autonomic dysfunction, motor symptoms, both simultaneously were 30% (56/184), 64% (117/184), and 2% (4/184), respectively.
