The PICOT question format is a consistent "formula" for developing answerable, researchable questions. When you write a good one, it makes the rest of the process of finding and evaluating evidence much more straightforward.
P: Population/Patient - age, gender, ethnicity, individuals with a certain disorder
I: Intervention/Indicator (Variable of Interest) - exposure to a disease, risk behavior, prognostic factor
C: Comparison/Control - could be a placebo or "business as usual" as in no disease, absence of risk factor, prognostic factor B
O: Outcome - risk of disease, accuracy of a diagnosis, rate of occurrence of adverse outcome
(T): Time - the time it takes for the intervention to achieve an outcome or how long participants are observed (Optional)
Example Questions:
