Locating evidence in literature depends upon asking an effective research question. Use the PICO mnemonic to build that question.
P I C O
P -- patient, population, participant
I -- intervention, therapy
C -- comparison (not always required)
O -- outcome
4 Types of PICO Questions
In children with respiratory infection, is the respiratory rate as effective as chest x-ray in detecting pneumonia?
In premature infants (compared to full-term infants), what is the lifetime prevalence of hearing deficit?
In patients with recurrent infection, do antibiotics, compared to no treatment, reduce recurrence rate?
In post-menopausal women, does hormone replacement therapy increase the risk of breast cancer?
