What type of information are you focusing on?
Frame (think out) your research question using the PICO method?
PICO was first developed in the medical field for clinical researchers and has been adopted by other subject disciplines.
PICO stands for (Population; Intervention; Comparison; Outcome)
PATIENT/PROBLEM - What are the characteristics of the patient or population or problem that you are focusing on?
INTERVENTION - What do you want to do with this patient or population or problem?
COMPARISON - Are there alternatives to consider? This could be an optional step.
OUTCOME - What are you trying to accomplish, measure, improve or affect?
If this is a clinical issue: Are you looking for therapy (treatment), Diagnosis, Harm/Etiology (identify causes for disease) , Prognosis (estimate patient's clinical course), Prevention?
QUESTION: Does the journal article provide what you seek using the PICO format.
See Cochrane Database journal article example.
