I think for most people who work with bash, the term "result" means the
numeric return code of the subshell command.

$ (echo foo; exit 3)
foo
$ echo $?
3

Also known as the exit code, this is a single-byte value that was
returned by the last command run in the subshell when it exited.

It seems like you might be talking about the output of the subshell
command (whatever data it writes to its standard output).

bash allows you to do a couple of things with that output.  The
most common are:

- pipe it into the input of another command
  (subshell) | command2

- place it into the command line arguments of another command
  command2 otherargs $(subshell)

- assign it to a shell variable
  foo=$(subshell)
