The Limits of Crossover in a Non-Fairy Ority Trial

I'd like to give twitter the first chance at questions if there are any. So I suppose the first question is a clinical one and you had sort of relatively balanced groups but a longer period of time in ICU and hospital for the CPAP group. Have you an explanation or a mechanism that you think you could postulate behind that? Yeah then if they especially. Marianne also mentioned it's the global interpretation of the clinical trial so there were some other secondary outcomes that are somewhat more objective that were supportive of the primary outcome.
