Hi Bilbo, im pretty sure the 95% Confidence interval is related the the range of the Hazard ratio rather than the probability of someone surviving 16m more.
I'm basing most of my knowledge off wikipedia (confusing)
and
http://www.biooncology.com/clinical-trials/clinical-endpoints/biostatistics
and
http://www.medicine.ox.ac.uk/bandolier/painres/download/whatis/what_are_conf_inter.pdf
In the example of 1st link, they had a hazard ratio of 0.76 with a confidence interval between 0.64 and 0.88, which looks much nicer. ie. 95% certain that true value lies between 0.64 and 0.88, with a good chance of it being in the middle, aka 0.76
Whereas PRR's announcement has a super wide Confidence interval. (and 0.17 isnt in the middle of 0.02 and 1.43)
They also mention that you need a p score of <5% to be statistically significant?? with P<0.01 as highly significant?
What does that mean with PRR's p-value of 0.07?
Thanks for the help guys, im still digging and trying to figure this out.
