Hello,
I have categorical data (high/low) on a protein which I am investigating its potential role as a prognostic utility.
I have run a cox regression with the categorical data and 3 year survival as outcome (dead/alive) I get a significant results (attached).
I then ran bootstrapping using the cox regression model for 1000 cases and get a significant result (bottom table attached) however I do no understand the output as the confidence intervals cross 1.
Is there anyone able to explain the bootstrapping output in SPSS for cox regression please.
Thank you
