This is a likelihood ratio test of the null hypothesis that all
coefficients except the constant are simultaneously zero. In your case
you have only one variable, so this p-value should be close to the
p-value in the column p>|z|, but it does not have to be exactly the
same, as the p-value in that column results from a Wald test.

Hope this helps,
Maarten
