  • Values are mean (SD) unless otherwise stated.

  • DMD = Duchenne's muscular dystrophy; non-DMD = non-Duchenne's myopathy; MND = motor neurone disease; T+D = tracheostomy followed by death.

  • Note that some patients may have more than one outcome.

  • 5-151 Difference between polio-body ventilation and polio-M/NIPPV significant, p<0.01 (Wilcoxon rank sum test).
