Does 100% of branch,conditional,expression and statement and 40% of toggle coverage means, there are unused or unnecessary signals/variables in code?

Coverage

Hi,

I got almost above 95% of all types of coverage except toggle coverage which is making my overall coverage low.
Does this mean that there are unnecessary variables used?

In reply to adharshh:

It could be unnecessary signals or signal widths larger than needed.
Looking at a few missed signals for toggle coverage will give you your answer.
