Should there always be a comma after "as a result"?
For instance:
This is done by using a database of patients and as a result the factors which have any significance are obtained.
This is done by using a database of patients and as a result the factors which have any significance are obtained.
should become:
This is done by using a database of patients and,be written as a result, the factors which have any significance are obtained?...
This is done by using a database of patients and, as a result, the factors which have any significance are obtained
