Biostatistics & Research · patient case question
In a PICO question comparing laser treatment with conventional scalpel surgery, what is the 'I'?
Patient case: Hypersensitivity, asthma and research design
Scenario: Three items.
Show answer and explanation
Correct answer: D. The laser treatment
- A. Healing is the 'O', the outcome measured.
- B. The scalpel is the comparison, the 'C', representing standard care.
- C. The patients form the 'P', the population or problem being studied.
- D. Correct. 'I' is the intervention — the new or tested treatment under investigation, here the laser.
Note: A well-built PICO question makes the search strategy almost write itself — each element becomes a search term.
