Tracheostomy remained an independent factor associated with longer survival (HR = 0.38, p = 0.029) in patients with stridor, also after adjustment for other confounders (autonomic onset, early stridor onset, early RBD onset) and although patients treated with tracheostomy showed a trend toward longer latency for stridor treatment from stridor onset.
