SEARCH UNIVERSITY LIBRARIES
While you will need to eventually address as many PICO(T) (Population, Intervention, Comparison, and Outcome (Time) components as possible, trying to search for all of them at the same time is seldom successful. This method generally results in getting zero results--despite the fact that evidence that answers the question does likely exist. To avoid the dreaded "0 Results,"
1. Search only one main concept at a time.
2. Combine two main concepts.
3. Begin to apply your limiters. Start by only limiting by publication date and preferred language. Too many limiters can also result in the dreaded "0 Results."
