1-3 tracheal resection
Mail   Print   Twitter   Facebook

 

The age of the patient did not seem to directly contribute to the mortality rate of this procedure.

The highest incidence of fatal outcomes is when the resection was 4 cm in length. However, larger areas of resection, did not appear to have a higher risk of death.

The P Value is greater than 0.05, meaning there is no statistical significance regarding death respective to prior surgery or not prior surgery.

I really enjoyed looking at your histogram for death and tracheal resection length. I produced the same graph on my report but I had two different histograms on two pages for death and no death. I like yours a lot better with death yes or no color coded on one graph. I think this is a lot easier to recognize and grasp. My two-paged graph didn't even show in my report so I'm going to try to do that way next time. It was interesting to me in this histogram that when the resections got into the 4 cm range, there life/death ratio was the closest to 50/50.

You state "However, larger areas of resection, did not appear to have a higher risk of death." I found with my report that in fact the larger the resection the higher the death. Perhaps summary statistics for this and or making a box plot of death vs resection would have helped to portray that. I also found it interesting that you had your numbers on the horizontal axis and yes or no on vertical axis. Mine was the opposite not sure I know how to switch it as you have done?
