To understand why, i think you have to know 2 data points 1) The first date (and then-current surgery schedule) at the point when the conference dates where announced. 2) The date (and then-current surgery schedule) at the point, when the doctor booked his/her travel plans. Both lists and dates will help you understand if changes in information also resulted in the changes of mortality (by rescheduling hard cases to a later date, for example). |
