No Difference in Sleep and RBD between Different Types of Patients with Multiple System Atrophy: A Pilot Video-Polysomnographical Study

Table 4

Respiratory parameters at PSG in MSA patients.

	MSA-C; (𝑛=11)	MSA-P; (𝑛=26)	Significance 𝑃 value
Sleep apnea, 𝑛 (%)	7 (64)	11 (42)	NS
Min SaO2, %	82.22 ± 13.24	81.69 ± 10.99	NS
Average SaO2, %	94.68 ± 1.69	93.79 ± 2.80	NS

NS: not significant (𝑃 value > 0.05), SaO2: oxygen saturation, MSA-C: multiple system atrophy cerebellar predominant, MSA-P: multiple system atrophy parkinsonian predominant, PSG: polysomnography.
