Result 1: HistCarina   [Info]
Right click to copy

This histogram above shows the frequency of Tracheal Carina Resection (TCR) at various ages. The graph could be used to see what ages are more likely to have this surgery. From the histogram, one can see that the middle ages are the most frequent for this surgery and is most frequent around age 60. This could clue in care providers about their patient population and prepare them to learn what is important for these ages during the surgery and care of the patient. 

Result 2: Histogramdeathresect   [Info]

The histogram above shows the relationship between Tracheal Carina Resection length and death. Care providers could look at this histogram and see that death is more frequent with a larger resection than it is with a smaller resection in this sample. This is what I would expect since the surgery is most traumatic the larger the resection.


Result 3: PropDeath/priorsurg   [Info]
95% confidence interval results:
p1 : Proportion of successes (Success = Yes) for Death where "Prior Surgery" = Yes
p2 : Proportion of successes (Success = Yes) for Death where "Prior Surgery" = No
p1 - p2 : Difference in proportions

p1 - p2634111010.0675596970.072355085-0.0742536640.20937306

The above confidence interval suggests that there was not a big difference in the proportions of death with prior surgery and death with no prior surgery for TCR patients. This would tell physicians and care providers that their patients who have had a prior surgery have no increased risk for death more than a patient with no prior surgery.

You stated "The graph could be used to see what ages are more likely to have this surgery." I think the graph shows what ages had surgery in the sample, but I'm not sure it can be applied to what ages are most likely to have surgery in the population; because this only shows statistics for the sample, not for the population.

I do like how you have the explanation of the graph next to each graph. How did you do that? I am only seeing one place to include my explanations and comments.

Perhaps it may have been helpful to see a histogram of the Tracheal Carina Resection length and death both yes and no. It appears the histogram only represents the ones who did not die but it would be helpful to compare the ones who did die as well.

I agree with your confidence interval, that is how I took it too. Yes, it is a tricky surgery which may take extra time to heal, but at lease you can have some hope that this doesn't cause death. Sallie
