Do You Have a Crossover in This Study?

Five patients who survived in the crossover group. If those patients would not survive would not have survived we would have a beautiful statistically significant difference between those two arms so and I don't regret that because the our aim is always to care for the patients. There is some signals in other studies and we are just doing a post-hoc analysis on that when they put a patient on look as and transport they kind of stop CPR.
