I am running a univariate Cox proportional hazard regression and I am not sure how I should interpret the obtained results.

In my model, I have only one single variable (X) and the overall model fit is statistically significant (p<0.05) with the following results:

**Null model -2 Log Likelihood**

90.738

**Full model -2 Log Likelihood**

84.473

**Chi-squared**

6.264

**DF**

1

**Significance level**

P = 0.0123

P = 0.0123

but the covariate "X" is not significant:

b -0.1048

SE 0.07542

Wald 1.9295

P =

**0.1648**

exp(b) 0.9005

95% CI 0.7768 to 1.0440

How should I interpret these results?

Thank you for your help!
