Results Leading Onto Other Results
A good place to look when conducting research is in the bibliography of a piece of research you have identified as useful. All journal articles or reports should contain a bibliography, and many databases have features such as Cited by and/or Related Documents. See the below example in Scopus.
You could also search for other articles by the cited authors, as it is quite likely they may have produced some other research which you will find useful. In some databases if you click on the author, it will list other research which they have conducted.
