Hello,

I am trying to show if there is any relationship between the different variables (weight, age, risk score) and freedom of re-intervention after a stent placement. Freedom of reinterevntion is a time depending value, so the more I think about it I think I should use cox's regression model. But on the other hand I am thinking weight/age/risk score and freedom of re-intervention are both continuous values so if I want to show a correlation between the two I should use the pearson/spearman? What do you think? Also if I am reporting the cox model, should I just report the hazard values and the p-values or may be more?

Thank you in Advance
