If you are interested in the back end time only, then you should be looking at the "Time to First Byte (ms)" value. You can get this in 2 ways:
1. In the requests table, click on the first request and see the value
2. Export the results to an excel and look for the column named "Time to First Byte (ms)"

You do mention that you are looking for "backend time vs frontend". Could you elaborate? eg: Are you trying to see how much time was spent in downloading v/s rendering? This may help the community give you a better answer.

Yes, I'd like to compare the backend time vs frontend based on Steve Souders post here:
